Description: DETERGENT COMPOSITIONS CONTAINING LIPASE AND PROTEASE FIELD OF THE INVENTION The present invention relates to laundry detergent compositions containing lipolytic enzyme, proteolytic enzyme, and surfactant, and the use of said compositions in laundry cleaning processes to provide whiteness maintenance and/or dingy clean-up. BACKGROUND OF THE INVENTION The inclusion of lipase in detergent compositions for improved cleaning performance is known, e.g. enhancement of removal of triglycerides containing soils and stains from fabrics. Examples are US Patent 4,769,173, Cornelissen et al. issued August 29, 1989; US Patent 5,069,809, Lagerwaard et al., issued December 3, 1991; PCT application WO94/03578 and HAPPI (Household & Personal Products Industry) No. 28/1991. In USP 4,769, 173 is disclosed a certain class of lipases consisting of fungal Upases ex Humicola lanuginosa together with strong bleaching agents in detergent compositions. An example of a fungal lipase in this patent is the lipase ex Humicola lanuginosa, available from Amano under the tradename Amano-CE. In USP 5,069,809 is disclosed the combination of strong bleaching agents with a lipase enzyme produced by cloning the gene encoding the lipase produced by Humicola lanuginosa and expressing the gene in Aspergillus oryzae as host for use in detergent compositions. In WO 94/03578 is disclosed an enzymatic detergent composition containing 10 to 20000 LU (Lipolytic units) per gram of detergent composition of a lipase showing a substantial lipolytic activity during the main cycle of a wash process. This lipase is selected in particular on its inactivation behaviour with Diisopropyl Fluoro Phosphate (DFP). Likewise, the inclusion of proteases in detergent compositions for improved cleaning performance is known. For example, protease enzymes are described in U.S. Patent No. 5,185,250 and U.S. Patent No. 5,204,015. In addition, bleach compositions containing protease having enhanced stain removal properties are also known, having been described in WO 94/10284, published May 11, 1994, by The Procter & Gamble Company. Commercially available protease enzymes include Alcalase®, Esperase®, Durazyrn®, Savinase®, Maxatase®, Maxacal®, and Maxapem® 15 (protein engineered Maxacal); Purafect® and subtilisin BPN and BPIST. Of the lipase enzymes, only the lipase derived from Humicola lanuginosa and produced in Aspergillus oryzae as host has so far found wide-spread application as additive for fabric washing products. It is available under the tradename Lipolase®, from Novo Nordisk. Gormsen and Malmos describe in HAPPI Lipolase as being the first detergent lipase with a commercially relevant cost performance based on the use of recombinant DNA technology on an industrial scale. In order to optimize the stain removal performance of Lipolase, Novo Nordisk have made a number of variants. WO 92/05249 describes the D96L variant of the native Humicola lanuginosa lipase improves the lard stain removal efficiency by a factor 4.4 over the wild-type lipase (enzymes compared in an amount ranging from 0.075 to 2.5 mg protein per liter). Example 20 therein describes the storage stability of certain of these Upases in liquid detergent compositions in the presence of the protease Alcalase®. Research Disclosure No. 35944 published on March 10, 1994, by Novo Nordisk discloses that the lipase variant (D96L) may be added in an amount corresponding to 0.001-lOOmg lipase variant per liter of wash liquor. The compositions therein are said to optionally comprise "one or more other enzymes, such as amylase, cutinase, protease, cellulase, peroxidase, and oxidase." Finally, detergent compositions comprising combinations of Lipolase and certain proteases are commercially known, for example in the U.S. Tide® and in Europe Ariel® (both brands sold by The Procter & Gamble Company). However, the benefits of whiteness maintenance and dingy clean-up on fabrics using combinations of lipase and protease , preferably low levels of D96L lipase variant in detergent compositions, has not been previously recognized. It has been found that lipase enzymes can be combined with protease enzymes in surfactant compositions to obtain surprisingly effective dingy soil clean-up and or whiteness maintenance benefits. Accordingly, it is an object of the present invention to provide improved laundry cleaning compositions using lipase enzymes, protease enzymes and surfactants. It is another object herein to provide a means for removing dingy soils from fabrics using laundry compositions containing lipase, protease, and surfactant. It is a further object to provide a means for maintaining whiteness of fabrics using laundry compositions containing Upase, protease, and surfactant. These and other objects are secured herein, as will be seen from the following disclosures. SUMMARY OF THE INVENTION The present invention relates to laundry detergent compositions comprising: (a) a lipase enzyme other than Lipolase; (b) a protease enzyme other than Alcalase®; and (c) a surfactant; and wherein further said compositions comprise levels of lipase enzyme and protease enzyme such that the whitening performance of said compositions is increased. Preferred are solid (preferably granular) laundry detergent compositions comprising: (a) a Upase enzyme variant D96L of the native lipase derived from Humicola lanuginosa; (b) a protease enzyme; and (c) a surfactant; and wherein further said compositions comprise levels of said lipase enzyme and protease enzyme such that the whitening performance of said compositions is increased. Also preferred are laundry detergent compositions comprising: (a) a lipase enzyme (preferably Lipolase and or a lipase enzyme variant D96L of the native Upase derived from Humicola lanuginosa); (b) a protease enzyme which is derived from a precursor carbonyl hydrolase by substituting a different amino acid for the amino acid residue at position in said carbonyl hydrolase equivalent to position +76 (preferably in combination with one or more amino acid residue positions equivalent to those selected from the group consisting of +99, +101, +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274) according to the numbering of Bacillus amyloliquefaciens subtilisin; and (c) a surfactant; and wherein further said compositions comprise levels of lipase enzyme and protease enzyme such that the whitening performance of said compositions is increased. The preferred lipolytic enzyme variant D96L of native Humicola lanuginosa lipase is preferably incorporated into detergent compositions at a level of from 50 lipolytic units (LU) to 8500 LU per liter wash solution. Finally, the present invention relates to methods for laundering fabrics to maintain whiteness and provide dingy cleanup, said methods comprising contacting fabrics in need of whiteness and dingy clean-up with an aqueous solution of a composition comprising lipase enzyme and protease enzyme at levels such that the whitening performance of said composition is increased. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All documents cited are, in relevant part, incorporated herein by reference. DETAILED DESCRIPTION OF THE INVENTION Without limitation by theory, it is believed that dingy soils are the result of combinations of fatty soils and particulate soils. Fatty soils comprise Upids, proteins, and pigments that are deposited over time on fabrics from contact with human or animal skin. The majority of lipids are secreted from the sebaceous gland as sebum. Proteins and pigments from skin fragments are liberated by the breakdown of skin cells. Particulate soils comprise mostly airborne soU and floor/ground dust. It is believed that sebum is the major soil present on laundry, and its removal is important because unremoved fat acts as a matrix to hold particulate soils. Further it is believed that compounds present in the sebum can oxidize to contribute to yellowing of fabrics. Particulate soils include topsoil and products produced during the incomplete combustion of petroleum products. "Dingy clean-up", as used herein, means the ability of a detergent composition to remove such dingy soil build-up, over one or more washes, resulting in a measurable improvement in fabric appearance. Whiteness maintenance is the monitoring of the whiteness of wash & wear fabrics over a number of washing cycles. A good performing detergent has a good whiteness maintenance profile, i.e. it ensures that the whiteness of washed fabrics is maintained at a high level during the complete life cycle of wearing & washing. "Whitening performance", as used herein, means the relative ability of laundry detergent compositions comprising both lipase and protease enzymes (as compared versus the same compositions comprising only protease enzyme or lipase enzyme, under whatever comparative test conditions are employed) to produce dingy clean-up and/or whiteness maintenance results. Lipase Enzvmes: Lipase enzymes which may be considered for inclusion in the detergent compositions of the present invention include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1,372,034. Lipases include those which show a positive immunological cross-reaction with the antibody of the lipase, produced by the microorganism Pseudomonas fluoresce s LAM 1057. This lipase is available from Amano Pharmaceutical Co. Ltd., Nagoya, Japan, under the trade name Lipase P "Amano," hereinafter referred to as "Amano-P". Lipases include Ml Lipase^ and Lipomax^- (Gist-Brocades) and Lipolase^ (Novo). The Upases are normally incorporated in the detergent composition at levels from 0.0001% to 2% of active enzyme by weight of the detergent composition. A preferred component of the detergent composition according to the invention is the D96L lipolytic enzyme variant of the native lipase derived from Humicola lanuginosa. Preferably the Humicola lanuginosa strain DSM 4106 is used. This enzyme is preferably incorporated into the composition in accordance with the invention at a level of from about 50 LU to about 8500 LU per liter wash solution. More preferably the variant D96L is present at a level of from about 100 LU to about 7500 LU per Uter of wash solution, and most preferably at a level of from about 150 LU to about 5000 LU per Uter of wash solution. By D96L lipolytic enzyme variant is meant the lipase variant as described in patent application WO 92/05249 viz. wherein the native lipase ex Humicola lanuginosa aspartic acid (D) residue at position 96 is changed to Leucine (L). According to this nomenclature said substitution of aspartic acid to Leucine in position 96 is shown as : D96L. To determine the activity of the enzyme D96L the standard LU assay was used (Analytical method, internal Novo Nordisk number AF 95/6-GB 1991.02.07). A substrate for D96L was prepared by emulsifying glycerine tributyrat (Merck) using gum-arabic as emulsifier. Lipase activity was assayed at pH 7 using pH stat. method. One unit of lipase activity (LU/mg) is defined as the amount needed to liberate one micromole fatty acid per minute. The D96L variant of the native Humicola lanuginosa lipase has the additional advantage of delivering a significant benefit in whiteness maintenance when compared to the wildtype lipase. Protease Enzvmes Protease enzymes are usually present at levels sufficient to provide from 0.005 to 0.1 Anson units (AU) of activity per gram of composition. The protealytic enzyme can be of animal, vegetable or microorganism (preferred) origin. More preferred is serine protealytic enzyme of bacterial origin. Purified or nonpurified forms of enzyme may be used. Protealytic enzymes produced by chemically or genetically modified mutants are included by definition, as are close structural enzyme variants. Particularly preferred by way of protealytic enzyme is bacterial serine protealytic enzyme obtained from Bacillus, Bacillus subtilis and/or Bacillus licheniformis. Suitable commercial protealytic enzymes which may be considered for inclusion in the present invention compositions include Alcalase®, Esperase®, Durazym®, Savinase®, Maxatase®, Maxacal®, and Maxapem® 15 (protein engineered Maxacal); Purafect® and subtilisin BPN and BPN\ Protealytic enzymes also encompass modified bacterial serine proteases, such as those described in European Patent Application Serial Number 87 303761.8, filed April 28, 1987 (particularly pages 17, 24 and 98), and which is called herein "Protease B", and in European Patent Application 199,404, Venegas, pubUshed October 29, 1986, which refers to a modified bacterial serine protealytic enzyme which is called "Protease A" herein. More preferred is what is called herein "Protease C", which is a variant of an alkaline serine protease from Bacillus in which lysine replaced arginine at position 27, tyrosine replaced valine at position 104, serine replaced asparagine at position 123, and alanine replaced threonine at position 274. Protease C is described in EP 90915958:4, corresponding to WO 91/06637, Published May 16, 1991, which is incorporated herein by reference. Genetically modified variants, particularly of Protease C, are also included herein. Preferred protealytic enzymes are selected from the group consisting of Savinase®, Esperase®, Maxacal®, Purafect®, BPN 1 , Protease A and Protease B, and mixtures thereof. Bacterial serine protease enzymes obtained from Bacillus subtilis and/or Bacillus licheniformis are preferred. An especially preferred protease herein referred to as "Protease D" is a carbonyl hydrolase variant having an amino acid sequence not found in nature, which is derived from a precursor carbonyl hydrolase by substituting a different amino acid for the amino acid residue at a position in said carbonyl hydrolase equivalent to position +76, preferably also in combination with one or more amino acid residue positions equivalent to those selected from the group consisting of +99, +101, +103, +104, +107, +123, +27, +105, +109, +126, +128, +135, +156, +166, +195, +197, +204, +206, +210, +216, +217, +218, +222, +260, +265, and/or +274 according to the numbering of Bacillus amyloliquefaciens subtilisin, as described in the concurrently filed patent application of A.

The hydrophobic portion of these compounds will preferably have a molecular weight of from about 1500 to about 1800 and will exhibit water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide.
