1. All models need to be defined inside an installed application or declare an explicit app_label. Furthermore, it isn’t possible to import them before their application is loaded. In particular, it isn’t possible to import models inside the root package of an application
2. The django.contrib.contenttypes.generic module is removed
3. django.db.models.loading is removed.
Turns out that since Django 1.2 the admin only invokes actions when
handling POST if the POST data specifically *doesn't* contain `_save`:

So this submit name was preventing `edit_permission` from acting on the
POST data since Django 1.2.
