Added a validation so that a user can only cast one vote. Wireframing in an attempt to make restaurant showpage look better
Added vote handling. A user can only have one vote on an item. If user votes opposite of their origin vote, it deletes the old vote and makes a new one. If a user tries to vote up twice, it counts it as an un-vote
Added view logic for votes to update icons properly in the view
