[Zope] Re - Making non-aware ZClass CatalogAware

[Anthony Baxter]

as a data point, I used this with an existing ZClass that was 
also a subclass of Object manager. After the upgrade, things
like 'objectValues' would no longer work in the ZClass instance
(they'd return no objects).
 
I didn't try to figure out why, I just threw away the changes. 

So yes, make sure you back up your Data.fs before you play this game.
