Convenience functions

languages :: Monad mo => GGHandler s m mo [Text]

Get the list of supported languages supplied by the user.

Languages are determined based on the following three (in descending order of preference):

• The _LANG get parameter.
• The _LANG cookie.
• The _LANG user session variable.
• Accept-Language HTTP header.

This is handled by parseWaiRequest (not exposed).
