Profile Page Styling

## Feature Implementation
- Profile Page Styles
- Devise Registrations Controller override
- Feature Spec for User Profile
This Devise Registrations Controller override simply allows the user to update attributes without being required to input the password every time. This is explained [here]( https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-edit-their-account-without-providing-a-password).
