Currently on the live site (and local i'm sure) a User can't change their vote. This should work like so:

Submitted Link: google.com, link score: 0

User clicks upvote, link score: +1
User clicks downvote, link score: -1

I think we should investigate [Thumbs_Up](https://github.com/brady8/thumbs_up). I previously tried using vote_fu and vote_fu_rails_3 but didn't have much luck.

Thumbs up would simplify the karma aspect of things and solve the one vote per link issue.
