LATGenerator: Fix NSUBJ type test
Add a Wordnet setup with a wrapper yodaqa.provider.JWordnet class
Add Wordnet-based LAT-from-LAT hypernomic generator

We expand existing LAT annotations with hypernomy generalizations
(e.g. inventor -> creator -> person -> ...) using a new LATByWordnet
annotator.  We do this based on the Wordnet database.

This also involves moving the LAT annotation from QuestionTypes
to TyCorTypes; LAT will soon appear in CandidateAnswers as well.
