Abound Theme Basic Integration

Started switching things over to the Abound theme.
Some Main Menu Icons

Added icons to some of the links in the main menu.
User Prefs Migration

Created a migration for the new user prefs, currently only used for
storing the color.
Color Switcher Database Lookup

The user's color preference is now looked up from the database when they
log in and that preference is used to load that specific style.
Currently, the style has to be changed manually in the database, the
picker is not ready yet.
Color Switcher Finished

The color switcher is now fully functional.
