Value binding issue sorted out on registration controller
Field validation working.
Both required and confirmation is working. I will probably want to refactor these at some point in the future into something a bit simpler, but for now this is wokring and highlighting fields that are invalid.

Right now I'm not stopping the user for submitting the form if things aren't valid. Need to think about what messages I want to show and how if I do that. Also right now when registration fails, I'm not really displaying the actual error message returned by devise. I need to do that, too.
