v1.2.0

Features:

• New awesome option userChrome.theme-material, check readme for more info.

Fixes:

• mf prefix has been changed to md for compatibility with the new option (you need to replace it in your custom.css if you use it).
• Added prefixes for preferences: color schemes now use theme, meaning only one theme can be enabled; user interface preferences now use prefix ui, you can use more than one (you need to recreate this variables with new names in the about:config page if you use it).
