Allow full themeing of mms via theme chooser

This redirects layouts to @color and replaces the hex that the theme chooser
cannot handle. It allows theme chooser themes the ability to theme the entire
app instead of just parts.

This is by @B_boytm I am just submitting it for him.

  PS 3: fix tabs to spaces
