WIP
Start on review side of finaid
Financial aid review team

Implement the review team:
* new permission in fixtures
* new team in fixtures
* implemented is_reviewer() code

Also switched to using natural keys in the permissions fixture, which
we should have been doing all along.
Escape messages; add form error message

* When displaying financial aid application messages, escape the text
  for security.
* If there's an error on the financial aid application form, display a
  message at the top so it's more obvious.

ADD migrations
Well, not completely remove it, but remove it from the global
list of context processors and just call it from the dashboard
view to update the context for that view. Not the most general
solution, but should work well enough.
