Issue #112: Prepare Stackless 3.5, fix test_dictviews, test_generator…

…s and test_xml_etree

Disable the recently added test methods test_copy() and test_pickle() in test_dictviews, test_generators and test_xml_etree. Theses test assure that objects can't be copied or pickled, but Stackless can copy/pickle them.
