Renamed Rating to Votes, and then added multiple ratings system initial structure: Image 1->n RatingPanel 1->n Rating 1->n Votes
Removed ratings from image index, started ratings panel controller.
Disable Turbolinks, because not entirely compatible with AngularJS. Reinvestigate whether or not to use Turbolinks later.
Auto_explain is removed in rails 4, so don't use it.
Rating Panel views and controller started. Needs rest of ratings functionality, including displaying rating and accepting votes. Also, should use bootstrap to style form errors.
