HTML* classes for cgi are now all new-style Add regression test for old behaviour: Lookup of a value of a HTMLProperty was possibly via getitem -- for old-style classes this worked because __getattr__ returned the __getitem__ of a newly created HTMLItem object, this does no longer work for new-style classes as these look up special method only on the class not the instance.
