OBSOLETE
SYNOPSIS
        string creator_file(mixed ob)

DESCRIPTION
        Return the name of the creator of a newly created object, i.e.
        the name of the user that is responsible for the LPC source
        file the object was loaded from. If the function returns 0,
        the object can't be loaded and is destructed again
        immediately.

        In !compat mode, the returned string serves as the initial uid
        (``cuid'') of the object. Objects whose cuid is the
        backbone-id will then get the uid of the currently active user
        as their userid instead.

        Under compat mode this function is called as well and provides
        the information returned by the creator() efun.

        If this function is not provided by the master object, no
        other object can be loaded.

HISTORY
        Dropped in 3.2.1, replaced by the _UID driver hooks.
