#12540: Add support for cross-database foreign keys and m2m

------------------------------------------+---------------------------------
Django's multidb support currently prevents foreign keys from referencing
foreign databases. This means the obvious use case of "put User objects in
the auth database" et al are not possible.
The full solution requires at least the following:
* Modifying ForeignKey to relax foreign key constraints if it is known
that the foreign key will be on another database
* Providing hooks to allow FK and M2M descriptors to look up the right
database to use
There has been [http://groups.google.com/group/django-
users/browse_thread/thread/74bcd1afdeb2f0 some initial discussion on
django users] about this subject.
