Likes

If God likes us, this will merge

Initial PR on the likes function ... Still needs several things that can be done in some other future PR's, these include

1) Board permissions for likes
2) Show liked and likied :) posts
3) Ajax to show all the likers of a post and to add/remove a like
4) potential optimization/consolidation on the querys, not sure

Sorry in advance for the permissions file, it got caught up in the eol thing and I can't stop it from committing the entire thing.
