Introduce a cleanUp/cleanUp: protocol based on the proposal from Mantis:

http://bugs.squeak.org/view.php?id=7244

The cleanUp protocol takes an optional argument to indicate whether we're doing an aggressive cleanup (which involves deleting projects, change sets, and possibly other destructive actions) or a more gentle cleanup that's only supposed to clean out transient caches.

Some subclasses may act differently depending on its value - for example, ChangeSet will only delete all unused and reinitialize the current change set if we're asking it to be aggressive."
