Removed usages of Gosu.button_down? in InputMapper allowing for 'virtual input' support, tacked on demo support (recording and playback of camera yaw and pitch along with all key events in Game.), Camera now sets @game_object.y_rotation instead of @game_object setting Camera.yaw in Camera.position_camera.
