Alpha 1.3 update

Changelog 
a1.3:
- increased player bounciness
- fixed bug in linerenderer so that it could draw the grapple effect over time again. Note: I am dumb and the solution was obvious
- added force to player on release of grapple, to give greater feeling of momentum
- missing the grapple will now briefly shot out the grapple before disappearing and playing a failure sound. Note: This was a pain in the butt
- score now increments by +4 instead of +1, which should speed up the incrementing process
