## About The Pull Request
Adds a new hairstyle called Short Bangs 2.
The hairstyle is basically an edit of the existing double buns, except
the hair buns themselves are removed.

## Why It's Good For The Game
More customization, variety and character flavor is great. Double buns
itself is a good hairstyle but some may not like the hair buns out of
personal preference or that it can look weird on non-human species like
felinids.
