Music, Sounds, and Combos!

Hi Everyone! Just wanted to let you all know that now, when things merge there is a sound effect that plays! Additionally, we now have a random array of gen 4 music that will be played, so no more of the same song forever. Finally, the game now implements Combos! They multiply your score, and you can tell if you have a combo going by the merge sounds. I will hopefully add a visual aspect to the combos at some point, but for now I hope you all enjoy :)
