Plugins Appearance Transformer

- Fixed bug from previous version where short morph UIDs like "Thin" caused an error
- Added fallback to using morph's display name if UID not found

- Fixed morphs being loaded by name rather than UID
- Fixed scale being changed on appearance load even when "Allow Scale Transform" not enabled
- Fixed "Genital Cutouts On" option being enabled in DecalMaker when it shouldn't have been

- Implemented Skin Color and Specular Skin Color in a simplified way (textures now use the skin's hue and saturation)

- Fixed demo scene pulling the wrong plugin version

- Added demo scene
