Plugins [Experimental] Alternative Futa

• The skin now matches the skin (including customizations) of the previous model.
  • Gen texture is still always FutaSimone
• Some error logging improvements

• Genital positioning is now controlled through morphs that can be tuned manually.
  • Names are:
    • AltFuta Bone+Mesh Y-Offset
    • AltFuta Bone+Mesh Z-Offset
    • AltFuta Mesh Y-Offset
    • AltFuta Mesh Z-Offset
  • I'm too lazy to learn Blender, so these are created by the plugin at runtime. Might not fully work properly.
• Material options are now saved with the scene
• Added some ignore rules for gen and pelvis colliders.

Minor update...

• Now enables controllers and collision for the testes
• Uses the FutaSimone gen texture by default.
  • This also means it uses the standard body shaders. No transparency but should work with tesselation.
  • I might add transparency as an option later, since the alpha blending could be used to even out the texture boundary
• Added comments to the code to document more of how it works internally.
  • I'm still fairly new to VAM plugin development, so I'm likely doing a lot of basic things wrong. Please educate me if you're willing. Do not be gentle.
