add vote model
i'm noob
Add vote_count to question
Add VotesController#create, which creates a vote given parameters

Need to work on error handling and bringing this into the interface,
but I want to do some work on importing from Stack Exchange first
Merge branch 'master' into votes
format answers
Merge branch 'master' into votes
Add votes display on question show pages
Refactor model vote logic into a concern
use select rather than where for vote counting
preload votes on answers
Merge branch 'master' into votes
Return an error if someone tries to upvote a post again
Update the upvote arrows on ajax submit
fix some build issues with votes
Merge branch 'master' into votes
Add Voteable#has_vote_by_user

This will easily allow us to check if a user has alredy voted on an item with
a given vote_type
Add votes_by_user
Add Question#votes_on_self_and_answers_by_user(user)

This will be used to look up for whether votes are active with less DB queries
rewrite the logic behind displaying votes on/off
