Swipe controls improved and refactored

- Created a new monobehaviour for swipe events. This is attached to the
_GlobalScripts since we need it always, not just ingame. And by
extension removed it from the GameLoop class.
- Created folder called Controls in which the mono and CameraControls
reside.
- The event onSwipeAction now has an fingerCount attribute which
designates the amount of finger where used to activate the swipe action.
Should hopefully work with every amount of finger unity supports. So 4
or 5.
