Title: WIP: Remove the __cmp__ method of BasicMeta and add a simpler __eq__ method.

The ordering_of_classes list is no longer used in BasicMeta.
This is the first step needed for the removal of ordering_of_classes.

This is obviously not ready for inclusion. It is here so I can get help with the many tests that are failing.
