Added META keywords and description processing. Now UdmSearch will find document first by default if there given words are found in keywords or description. UdmSearch stores keywords and description in database. One can easy add it into search result. Added TitleWeight, BodyWeight, DescWeight, KeywordWeight and UrlWeight indexer.conf command to define the 'weight' of each word in the different parts of the document.
All weights are bit OR'ed if word appears in different parts at the same time.
Configuration samples are included. Added 'FollowOutside' indexer.conf command to allow indexer follow outside servers given in indexer.conf. Should be used carefully with MaxHops limit. Indexer will use HEAD instead of GET http method for URLs that matches regexp. It means that the file will be checked only rather then downloaded.
