The Inbox: ReleaseBuilder-dtl.198.mcz

The idea here is to let an MVC project be the parent of the active Morphic
project like this:

Project topProject isMVC
ifFalse: [ (MVCProject new name: 'The root project') beTopProject ]

Thus an unrecoverable error in Morphic will first drop into an MVC debugger
before giving up and falling back on the emergency evaluator.
