I'll take a crack at a general package that adds registry behavior to  
the dock menus, and probably while I'm at it, since I've done this  
sort if thing before, see what can be done about the other menus that  
provide points where we would all benefit with flexibility.

The world menu currently supports a registry for Open.

Once the work is done I can publish 2 packages:
   1.  Desktop background loader that uses menu registry to install  
(and no longer collides with existing code)
   2.  A menu registries enhancement so we cross this bridge more  
smoothly in the future.

My question remains unanswered however, about how do I make this  
happen?  Just put it all in Squeak Source?  What really belongs in the  
inbox then?
