==================== Summary ====================

Name: System-dtl.170
Author: dtl

Ancestors: System-dtl.169

Remove Morphic dependencies from Project>>okToChange.
Add Project>>prepareForDelete and MorphicProject>>prepareForDelete to handle Morphic specific cleanup actions.

Remove some apparently unneeded logic by changing from this:
        ok := world isMorph not and: [world scheduledControllers size <= 1].
        ok ifFalse: [self isMorphic ifTrue:
                [self parent == CurrentProject
                        ifFalse: [^ true]]].  "view from elsewhere.  just delete it."

to this:
        self parent == CurrentProject
                        ifFalse: [^ true].  "view from elsewhere.  just delete it."
