fix the heightmap proxy caster guy and also asteroid belt now (#1002)

## Minor features
- Added an option to use a detail for asteroid belts, instead of just
procgen.
- Also added asteroid belt options for gravity and random orientation.

## Bug fixes
- Fixed the proxy shadow caster on heightmaps, so they cast shadows onto
other bodies better (fixes #1001)
