EmberPawn updates

Removed alot of obsolete functions

Added velocity pinching to jump (upon landing)

Doing a ton of jumps one after another will result in bunny hopping
fatigue like in BS.

Bugs:
-- Legs go coocoo
-- Doing a jump, landing, and immediately using grapple will apply
pinching to grapple as well. looks really bad

Needs alot more tweaking but we have it atm. function is
JumpVelocityPinch if you wanna check it out (completely commentated)
