Updated to latest dependencies

Removed wordnet from .gitignore since it's not getting created by jwnl-prime

@mssammon @khashab2 let me know when the new jwnl-prime is added to illinois-edison (we need to do that before we accept this merge)

Sorry for delay. I'll try to finish Mark's PR as soon as I can.

mentioned in commit d9c1eec9

Status changed to merged
