Changes to collider behavior

Browse Source 
The collider now levitates above the ground, which makes small obstacles a non-issue. The raytest also helps the collider stick to staircases, so players don't jump off anymore.
Crouching now changes the collider to a smaller version, so now there is actual functionality to crouching.
I also removed the anchor from corpses of network players. I'm not entirely sure why this was done, but removing it doesn't seem to break anything.
