Title: updated lexical category mapping 

previous mapping seemed wrong (admittedly from very brief test) -- for instance this failed before on synsets in the second line.

>> adjectives = WordNet::AdjectiveIndex.instance; nil
>> adjectives.find("tall").synsets.each {|x| p x.words};nil

it could not find the corresponding dictionary file since pos in Lemma was "a" and hence the dictionary file read from in the Synset constructor was "data.#{SynsetType[pos]}" == data.#{nil}
