Prevent "bad" votes by adding a wait timer

[grepsedawk]

For now, this can be implemented in elm directly, I'm thinking somewhere within https://github.com/Mingosio/celebrity-picture-rater/blob/master/app/javascript/Voting.elm#L67-L68, basically the equal to a setTimeout to disable the newest loaded vote, then re-enable the actions after a few seconds.
Also with this piece, it probably makes sense to add some visual cue like a green border flash or equal to depict the chosen image.

Planning on doing this myself, but really anybody that wants to pick up some elm can pick this up.

I could add a time to any new model and in NewVote set it, then not allow any actions until the time limit is met.
