Plugins + Scripts Light Options

• Prototype implementation for clothing layer selection.
  • By default, VAM renders clothing into layer 0, which made it hard to move a character completely into another layer for layer filtering. Fixing this required adding a separate SkinWrap, similar to how multiple states work (i.e. normal/exposed) on some built-in clothing.

There's a lot of room for bugs with this one. Let me know if it doesn't work right for you!

• Added toggles to non-session instances of LightOptions that toggle which game layers are affected by the light.
  • Note: by default everything is rendered on layer 0
• Added a new script, LightLayerEditor, which can be added to atoms to modify which layers they're drawn to
  • For People
    • Use the sliders for skin and hair. The mesh renderer settings don't do much.
    • There is no easy way to change the layer for clothing, unfortunately.
  • For CUAs
    • Use the mesh render sliders (or the 'all')

• Added shadowNormalBias (directional light only) and shadowNearPlane
• Tweaked slider quick-button settings
• Added a bit of additional documentation

• Can now be added as a Session/Scene plugin and will affect all lights present or added.
• Shadow resolution now goes up to 16, and each step represents a power of 2 (starting with 2^0 at 1)
