Changes in here look good to me! I'll defer to @lmorchard for doing a final r? and merging. Thanks!

I've been using this branch with a django 1.5 project with a custom user model. Problems encountered:

• Using User = getattr(settings, 'AUTH_USER_MODEL', 'auth.User') in models.py is correct for defining models, but breaks when the accessing user objects (this occurs once in models.py) as in this case User is a string not a class.
• Every other file imports the standard User model; if User is needed, it probably needs to be imported something like this:

try:
    from django.contrib.auth import get_user_model
    User = get_user_model()
except ImportError:
    from django.contrib.auth.models import User

• Custom user models don't guarantee a username field, which is used all over the place. One way around this is to use User.objects.get_by_natural_key(username_or_similar) but this doesn't gel with get_object_or_404. See https://groups.google.com/forum/#!topic/django-users/8SLAr6JGXu4
