JUMP + bug fixes

For the last time… pleaaaaaaaaase be over
-Significantly reduced ignored jumps
—Jumping consecutively keeps you at max speed
—Jumps on moving platforms that travel fast will be ignored still
—X and Y velocities are processed seperately
-New method for box-facing direction sprite changing
—It’s possible to get the arm gameObject without using the inspector
really easily!
-Rigidbodies on checkpoints (just in case)
-Renamed rocketJump.js to BoxbotJump.js
