Model and file structure changes

Deleted registration app since clashing with the date_app models.  Created media file.  Deleted html files since we will be building a new frontend layout.

I'm starting to work on login/registration and the first part of the profile.  I'll be working off the models in this pull request.  We can discuss at noon.

Bryan, I deleted the registration app for now.  Since we had built in the Dater model I kept getting errors when trying to migrate.  We can change it back later.
