Is your feature request related to a problem? Please describe.

Some copied objects have links to data out of the data base, linked by id or uuid.
When object cloned, it has new id/uuid.
To copy external data user need access to origin id/uuid of object.

Describe the solution you'd like?

I suppose to add origin parameter to pre_clone_save/post_clone_save signals.

To do this, in function make_clone in mixin.py we need to make these changes:

    -pre_clone_save.send(sender=self.__class__, instance=duplicate)
    +pre_clone_save.send(sender=self.__class__, instance=duplicate, origin=self)

...

    -post_clone_save.send(sender=self.__class__, instance=duplicate)
    +post_clone_save.send(sender=self.__class__, instance=duplicate, origin=self)
