Invisible Girl [ExtraMod] V2, EM0.79

Big thanks to @sby and to @RokPhenix for providing solutions to the bug making this mod incompatible with moreclothing.

While the mod still can't be loaded via MC, it can now be loaded alongside it. Meaning, that after MC has loaded you can now load Invisible Girl and dress her up as you see fit.

I also made a few code improvements, made it so there is no char data for the NoPenis versions, and added invisible art for all skin types.
