Adds some bits that help make django.contrib.auth a bit more useful.
Group gains a 'rank' field, that can be used to rank groups (useful where groups need to be able to be limited to view only groups 'lower' than they are).
Group gains a .duplicate() method, that will duplicate a group, including all of it's permissions.
- User gains methods for custom permissions:
These will use the current permissions, but also allow for methods to be added on the object/class being tested, which can permit or deny access according to custom rules. I use this for instance to only allow staff to view other staff who work at the same location(s).
Future: * Configure using data from DJANGO_SETTINGS_MODULE * Unique email addresses * Non-nullable email * Index on email * Random username on save (or email?) * email in template (?)
