I think this change set is  long overdue, but there's one thing I'd like
to add...

The one place I touched the base classes in Connectors is in
#addedOrRemovedSubmorph:, where I add a notification
	aMorph noteNewOwner: self

This is important for those Morphs that are sensitive to owner changes.
We already have some similar notifications (#intoWorld:, #outOfWorld:,
#justDroppedInto:event:), but lack a general notification.

That is,

in Morph>>addedMorph: aMorph
we should add:
	aMorph noteNewOwner: self
	
and in Morph>>removedMorph: aMorph
we should add:
	aMorph noteNewOwner: nil

The attached change set makes these changes.
