Profile Page Styling

## Feature Implementation
- Profile Page Styles
- Devise Registrations Controller override
- Feature Spec for User Profile
@irmiller22 I just realized that this whole `devise_parameter_sanitizer` is basically equivalent to Rails' strong parameters... my bad. But I'm still confused why we need all of this code - are params not getting through to the underlying `Devise::RegistrationsController` properly, so we needed to override this? 

This solution feels more lightweight to me as well: https://gist.github.com/kazpsp/3350730
