Added Q for end of Game during Gameplay

Added IsItEndOfGame() function that checks every cycle for an end Game
Event. For now that event is pressing the Q button at any time during
the game. It just loads the Main Menu again. Application.loadlevel(0).

+Issue, after selecting Single player, or Multpayer mode, Map loads, but
nothing else loads. No GUI, no Players. I am thinking it might be that I
am improperly loading the main menu scene, but before I try anything on
my side of things, I would like your guys' opinion.
