Django admin command to "fix permissions" (create them properly for proxy models). This is needed because of the following bug in Django (not fixed as of 1.6): https://code.djangoproject.com/ticket/11154
# -*- coding: utf-8 -*-
"""Add permissions for proxy model.
This is needed because of the bug https://code.djangoproject.com/ticket/11154
in Django (as of 1.6, it's not fixed).
When a permission is created for a proxy model, it actually creates if for it's
base model app_label (eg: for "article" instead of "about", for the About proxy
model).
What we need, however, is that the permission be created for the proxy model
itself, in order to have the proper entries displayed in the admin.
