making the nigeria formslogic use tuples instead of dictionaries so we can control the order in which the responses are generated more easily.  Also changing the way required field validation works to get it to actually decide if it's requried from the formtoken.  This means that this part of validation could be moved up to the forms app, but this move hasn't been done yet because it will prevent us from providing more helpful messages on the registration form.
