v0.5 - Added another player. (You spawn him by pressing enter.)

		
			     - He has twice as much health as player one and he is much faster, but shoots out only one bullet at a time.

     - Lives are shared between players, however health is not. (The healthbar down below shows the player one's health, still working on
       making a healthbar for the other player.)

     - His bullets are green instead of red, and emit a different sound.
