Further physics improvements [SEE DESC]

This was mainly focused on pickups, but it works for other things too.

* Entities no longer clip through blocks positive-vertically (this fixes
pickup issues as well).
* Entities lie flat against a block when they hit it.
* Reduced entity (mainly pickup) block clipping in non vertical
directions.
