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

[Sockssq]

This pr would be a great way to allow mutantraces to have more customization while we wait for the mutantrace. As a person who has many mutantraces I personally believe that this would be a good step in giving mutantraces more customization while the mutantrace rework is in works.

A bald mutantrace is nice, but hair is one of the only things you may remember them by, since the mutantrace rework isn't here yet.
