Plugins UVSwapper

Fixed a bug that prevents using UVSwapper as a dependency

Now you can generate the genitals textures by loading the torso texture. The color may be a bit offseted if your atom is a male, but it works great on female atoms.
Fixed a bug where the conversion doesn't work if the atom has a name with special characters.

• Most of the the texture joints problems were solved
• Solved the nail transformation
• The output is now .png
