Add Species Lookup Tool that uses Perl with BioPerl and Ensembl

Usage:
    perl SpeciesLookup.pl SpeciesName ReturnCountLimit

    Will print to standard out the list of species as a JSON Object.
    Probably worth piping :)
Fixed SpeciesLookup tool and added new GeneLookup Tool

Usage:
    perl GeneLookup.pl ExactSpeciesName DescriptionLookup
