Bug 44017: Cleanup ResourceLoader mess

add groups to ensure bottom scripts get loaded in their groups (allows
us to separate special page js from normal js)

stylesheets/modules/mf-cleanuptemplates.css was being loaded twice
make mobile.styles be added automatically

mobile.action.edit was being loaded twice. Doh.
