Create a user and a user settings member API with user creation.

The user API is the public API and the settings API is the private API
only accessible to the logged in user.

The API has been designed to mirror the 1%CLUB website profile / settings
designs. It currently uses the standard User and UserProfile models from Django
1.4 which means some of the fields read-only. These fields can become writable
fields when we move to Django 1.5 and create a unified User model.
