Fix dispatching in the pretty printing module....

Fix dispatching in the pretty printing module. Search for the best method to use for pretty printing an object now no longer prefers any registered printer in type_printers for the class or any of the base classes over a _repr_pretty_ method defined in the class or any of its base classes. Instead the mro is walked, looking for both registered printers and _repr_pretty_ methods, so that the inheritance hierarchy will be taken into account.
