Fixed jump and movement. However, velocity.x still zeroes on landing for some reason. Moving to PC because I don't have my mac charger with me.

Got the predictive line working and have integrated all GMTK jump values into better jump settings, however, characterJump still needs to be rewritten.

Implemented jump from GDC talk Building a Better Jump ( https://www.youtube.com/watch?v=hG9SzQxaCm8&t=784s ) along with drawing the curve of the jump and many EditorGUI elements.
