[svn] Add user registration and user profiles.

Used modified versions of django-registration and django-profiles , both on bitbucket.

The Person model is now set up as the profile for auth.User s.

I set up a requestcontext so that settings is automatically passed to every template, no need to repeat ourselves in views. However, this needs to be refined: I will soon change it to only pass a subset of settings. E.G. we do not need to be passing the DB login and password!
