Ah, right, Tim brought that up. The solution to that is to create a
subclass of Panel -- like MouseToolbar is, and EditingToolbar will be -- 
and use that as a control. So, you have:

 MainPanel.addControls( [ 
  -> Control.MouseToolBar
  -> Control.EditingToolbar
 ] )

deactivate on these can probably even be implemented on the Panel super
class -- deactivate simply iterates through this.controls and turns them
all off, and subclasses can then change display properties appropriately.

So, I've just done that -- now anything that subclasses off panel can
be used as a 'tool' in a panel. When panels are deactivated, they
dissappear, and their buttons no longer have any affect: all the
controls on them are turned off. In the process, I also  added support
for a defaultControl option. That's committed as 2629.
