Requests from last night:
- Implemented "isFavorited()" check on QuestionItem
- Implemented "haveUpvoted()" check on AuthoredTextItem
- Added "upvote(<item>)" call on QAController
Fixed upvote() to correctly generate UniqueIds for upvotes, preventing duplicate upvotes from a given user on a given post.
Merge pull request #140 from stravant/master
