I committed your MCConfig changes to trunk. Thanks! :)

But I'm not so sure about the changes to MC, as below.

Did you verify it even works? I don't think MCPackage>>unload is actually used when unloading a package. A better place would be MCPackageManager>>unregister and MCPackageManager class>>forPackage:.

Also, this introduces a hard dependency on MCMcmUpdater into the Monticello package. So this should at least be protected using

	Smalltalk at: #MCMcmUpdater ifPresent: [:updater | ... ]

or using some other mechanism of decoupling.

E.g., I see MCPackageManager class sends "self changed: #allManagers" whenever a package is added or removed. Maybe listening to that would be better than adding these explicit notification?
