Rebalanced stats

Adjusted engine power variables.
They were set 1.0 on every class, reducing speed on higher speed classes.
They should now scale from 4.0 at toxic to 2.0 on zen.
Overall should be buffed

Attempted to fix collision and shadow

Redid FBX import from blend file. The object scaling was not normalized, which resulted in a bloated hitbox and jank.

Removed box collider. (It creates an invisible imoveable obstacle on the grid)
Removed mesh collider. Hoping the game autogenerates a new one since collissions didn't seem to support the ship on the track consistently.

Changed collision to box collider

Fingers crossed this version is stable.
