Bastien Montagne 5610ccdc08 Add a callback to IDTypeInfo to allow preservation of some data accross memfile undos
This is essentially adding that new callback, and using it only for already
existing Scene's 3DCursor.

Note that the place where this is called has been moved again, after all
have been lib-linked, such that those callbacks may also work on ID pointers.
