Fix Shadows (#686)

<!-- A new module or something else important -->
## Major features
-

<!-- A new parameter added to a module, or API feature -->
## Minor features
-

<!-- Some improvement that requires no action on the part of add-on
creators i.e., improved star graphics -->
## Improvements
-

<!-- Be sure to reference the existing issue if it exists -->
## Bug fixes
- Shadows glitch out way less
- Custom planets now can have better, longer shadows (using
ProxyShadowCaster and ProxyShadowCasterGroup from existing details and
in bundles)
  - Shadows no longer jitter
- Note: short-distance shadows still cast from planets behind suns.
However, this also happens in vanilla, so it is not fixed here
