After pondering about a while, I think this is probably a very good  
solution. It should help us reduce the package interdependencies  
quite a lot, at least on the Python-only level.

It should also add meaning back to the "zope.app" namespace.

Note that I've seen checkins that add deprecation warnings. Even  
worse, they're talking about removing stuff in the future. I thought  
we had reached the consensus that we weren't going to remove stuff  
anymore. In other words, that we were never ever going to break  
backwards-compatibility again.

I think we should just not raise any deprecation warnings at all.  
Just the imports for BBB and be done with it.
