Title: SemcorCorpusReader was returning incomplete sense information

semcor.py was creating lemma sense tags as strings of the form `.`, which is incorrect: the sense number is actually POS-specific. With this patch, SemcorCorpusReader tries to retrieve the Lemma object directly from WordNet (using the sense key). If that fails, a string of the form `..` is given.
