updated for version 7.3.1047

Problem:    Python: dir() does not work properly.
Solution:   Python patch 8.  Add __dir__ method to all objects with custom
            tp_getattr supplemented by __members__ attribute for at least
            python-2* versions.  __members__ is not mentioned in python-3*
            dir() output even if it is accessible. (ZyX)
