Much cleanup for the gradApplication schema:

* Added list of countries. Not sure where this should live
     eventually, but for now it's here.
* Made the race/ethnicity match the actual application.
* Changed weird "yes" and "no" boolean fields to single boolean values.
* Enums... enums everywhere.
