Addmin RFR! (this is our previous branch plus the admin and all passing tests :)  )

Nice use of the `be_x?` matchers in RSpec!

Here, though, I wouldn't just test that a user is an admin if the role is admin.  In acceptance tests, you really want to test user features, not implementation details.  An admin doesn't care how they're granted access to destroy a character, for example, they just want to make sure they can destroy a character.

I'd instead have a test where a user tries to complete an admin-only action and receives an error message.  Otherwise, this test could pass perfectly well but without the proper `before_filters` and view logic, a non-admin might be able to perform admin functions.
