Non-Default, Default, Addons and Heterochromia options
Heterochromia does not require a mesh
CHANGES:
I've removed the mermaid and vampire options as I couldn't get them to work and I wasn't very proud of how they looked. This means only Human (Default and Non), Pets (Default only) and Aliens (Default and Non) are available.
Removed some of the uglier addon options, as well as the ones that were too similar to default colours.
