Rewrite the ACL queryset filtering to move most of the
computation to the database manager view the ORM.
Add support for cascading access control checking.
Update the .check_access() method to work as a front
end of the new .restrict_queryset method. The workflow
for access control now follow Django convention of
first generating a queryset and then attempt to .get()
the desired element of the queryset.
This update also allows restricting a queryset by related
fields which can be Generic Foreign Keys.
