Changelog - Update 20

Main Features:
-You can now activate physics based shoulder lock anywhere on your body, shoulders, chin, hips, forehead, etc. Hold your gun's stock near your shoulders, and double tap your hand's thumbstick to activate shoulder lock. A blue circle will show up inticating the shoulder lock position. Double tap again to deactivate shoulder lock. The shoulder lock position is fixed based on where you activate it, so you need to position your gun to your desired position first.
