Title: Fixed #18306 -- Deferred models should automatically issue update_fields...

Ticket: https://code.djangoproject.com/ticket/18306

Is an initial patch, run all test cases mentioned in the ticket.
I added documentation, where I felt I should be, but I'm not sure.

The only thing not clear to me, as it should behave `_state.update_fields`.

* Normal case, save all fields -> this attribute must be `None` (or all fields?)
* In all other cases, filled with the result of `update_fields`.
