Don't check for DO_NOTHING in the delete rule registration method.
...
It is already checked before it is invoked. This saves the ugly import
of DO_NOTHING inside document.py.

Use multiple objects in the test.
...
This is to ensure only the intended subset is deleted and not all
objects.

More the deletion code over to the QuerySet object.
...
The Document object doens't have any delete_rule specific code anymore,
and leverages the QuerySet's ability to deny/cascade/nullify its
relations.

Make the nullification an atomic operation.

This shortcut works now, since hmarr fixed the unset bug in dev.

Added initial implementation of cascading document deletion.
...
The current implementation is still very basic and needs some polish.
The essence of it is that each Document gets a new meta attribute called
"delete_rules" that is a dictionary containing (documentclass,
fieldname) as key and the actual delete rule as a value. (Possible
values are DO_NOTHING, NULLIFY, CASCADE and DENY. Of those, only
CASCADE is currently implented.)
