Jump, Tether

Jump
- Almost increased jump by double. Still working on it. Going to try to
replicate Space Marine

Tether
- Made transition from tether to nontether status to be smooth. There
should no longer be a velocity 'drop' after letting go of tether
- ^ Additionally, this makes chaining grapples alot smoother and a more
enjoyable experience
- Decreased tether length to 500. Seems to be an acceptable size, will
need to change velocities to conform with velocity being maintained
through grapple chains
