Capes (hopefully), based on Tinkers, and more.

Mainly reformatting, but the capes are hopefully going to work as well.
The capes are heavily based off Tinker's Construct's code (although it's
wigging out for me about the abstractclientplayer class, might be a derp
with forge or something)
Oops!  I forgot the TODO list!

The TODO is by SilverChiren.  I've added some stuff to it.
