[CLOSED PR] Wig glue trait that allows mutantraces to wear hats and hair

[klushy225]

I think it would be difficult to remove this feature. Not mechanically, but ah, it would probably cause a big stink when a feature that people have been begging for is removed. I more so meant easy to remove as in, letting the mutantrace rework handle mutantrace hair if it does without this trait.
