retailer sites

- homepage carousel now sets the background for the retailer inline (makes
  more sense than having to add a class in css for everyone)
- Implemented rules for setting lang and prov (not writing them out here)
- Fixed links to use App.CurrentUserLanguage not App.Lang

fixed issue with auto setting lang + prov + hide about link

- about link is hidden if the retailer doesn't have about us content
