- Changed vote date type to integer
- True votes are now 1, False votes are now -1
- Added option to store the vote count on the voteable table
- Used code from other vote_fu fork http://github.com/kandadaboggu/vote_fu
- Most features outside of the changes are untested
- Renamed to ThumbsUp from vote_fu.

- Cleaned up some dead code, some shitty code, and made a few methods take up quite a lot less memory and time (voters_who_voted).
