[Philipp von Weitershausen]

Log message for revision 72437:
  Make isclass() check a bit more tolerant.  The metaclass of a class doesn't have
  to be either type (new-style class) or types.ClassType (old-style class), but it
  can also be a subclass of either one.
  
  This tolerance is needed if we want to grok ExtensionClasses :).
