Switching back to using a resources route allowed me to simplify the highscores controller a good amount. Allowing respond_to/respond_with to do their magic.
Refactored player move evaulation into a nested object of window.spark with it's own methods (isYahtzee,isTriplePoints,isSinglePoints,isHotDice).Looks much better than the giant mess of nested if/else statements directly on the dice click event. This should make things more readable and hopefully testable.
