-  Python3 support fixed by pib (Paul Bonser) - thanks a lot!
-  Fetch and execution of vas changed - empty result should be ignored,
   and yield isn't used now. This should make error messages clearer. [robinharms]
-  Checks for containment, interface, permission etc moved to ViewAction object, since
   they weren't performed if the object was called directly. [robinharms]
