Physics: Box corner collisions are bad, need a rethink. #693

Problems:

Sticky. Circle and Box colliders take a while to get around them
Sensitive. If you make a platform of boxes and slide another box along them, it will jitter as it meets the corners of the platform boxes.

I think, for AABB boxes, one thing is just to bias restitution in the direction of the least amount of overlap (I.e. only push away one one axis, and the axis is the shortest one). Essentially be less clever and it'll probably look ok.

I think with the changes last made around iterative solving, this might work for the platform problem.
