Morphing Clown Mask!

In short, this is a small update in witch you can reskin the clown mask. Currently it has 4 options, which are the following:
1. The normal clown mask(True Form)
2. The female clown mask(The Feminist)
3. A new clown mask based of the joker(The Madman)
4. A new clown mask(The Rainbow)

I ran it on a local server and tested it, everything worked fine except that I cannot figure out how to make it auto-update when you wear it on your head while changing it, otherwise you have to remove and re-equipped it.

Here are some pics for your enjoyment ladies, gentlemen, and....that wierd guy in the back.
