[gedit/libgpe] Python: Handle the old API for config dialog creation.

[Steve Frécinaux <sfre src gnome org>]

commit 55db35a41bdbcbb82bb7b9a6d526768ffb0a2284

    Python: Handle the old API for config dialog creation.
    
    We now override do_create_configuration_dialog and do_is_configurable
    the same way we do for the other methods, so we can be backward
    compatible there too.
