Tameable Arachne

I decided to jam in some other orphaned materials after getting more of an idea how this stuff works and making other small changes. The name of the mod should change slightly in the menu and there are now six new harpy skins for tame and untamed.

By the way, now that I understand that system, it shouldn't be a major pain to add new skins! If you want to contribute, please stop by the github and submit. I'll be sure to credit people as it comes along when and where I can, if you want that.
