Gitter Dark is now on https://github.com/viluon/gitter-dark!

Stuff changed:

• Square avatars
• Grey backgrounds for side panels and chat
• Open Sans font
• Text input area has a slightly higher font size
• Buttons are blue by default
• Unread messages badges are blue
• Commits use yellow and a transparent background instead of dark violet
• Dropdowns, menus, and autocomplete are grey with white text

This style is an adaptation of http://freestyler.ws/style/131921/ylluminarious-s-dark-gitter, which is in turn an improvement over http://freestyler.ws/style/118494/matu-s-dark-gitter, which is in turn derived from http://freestyler.ws/style/118492/dark-gitter.
