Hair Fixes and Additions <3 (#2953)

## About The Pull Request
This PR does three things: It fixes the Dreadlocks hairstyle as its back
side sprite was misaligned, adds an alternate version of Dreadlocks that
plays nicer with muzzles and non-human faces, and adds a completely new
dreadlock hairstyle sprited by yours truly. (P.S. sorry if I fuck
something up, this is my first PR)
## Why It's Good For The Game
It's a quality of life fix for an underrated hairstyle, and something
that I've heard other people be vocal about as well, so I figured I'd do
something about it. Plus, this adds some extra variety with the extra
hairstyle. <3
