NEW CONTROL SCHEME IMPLEMENTED
NEW CONTROL SCHEME IMPLEMENTED

REMOVED:
	strafing
	key-based rotation

MODIFIED
	mouse-based control scheme:
		*the player's rotation now follows so that the player always 'faces' the where the mouse pointer is
		*firing is no longer the space key it is clicking the mouse
		*no more strafing
		*only backward and forward motion

this control scheme should be better for navigating the obstacles on a stage
