This adds two new major components: wn.morphy for English lemmatization and wn.web for a basic web server. Other improvements include methods for getting relations with the relation names and not just lists of targets, a progress bar for wn.lmf.load(), further customizability for queries regarding normalization and alternative forms, and some bug fixes.
Thanks to Tom Aarsen for an inspiring first draft of the wn.morphy module and to Diego Palma for the wn.lmf.load() progress bar.
