* Add FlatUX Theme, Remove Retired Themes
With some help from @gouchi, I decided to try and add the FlatUX theme, which has been in the retroarch-assets repository for years. FlatUX was designed to merge the FlatUI and Retroactive themes into a single, unified design.
With the addition of FlatUX, the Retroactive and Neoactive themes will be retired. This PR removes them both from the menus. The theme files will be removed from retroarch-assets, but are archived on baxy-retroarch-themes.
