[Pharo-project] Apparently removeSelector: does not dirty packages...

For example Workspace removeSelector: #embeddedInMorphicWindowLabeled:! does not make the package dirty. This can be normal because this is a low level API method. Now this expression is saved in the changeset when we remove a method. So the task to do is: - check if there is another API method that raise the correct notification of changes - change ChangeSorter to use this api http://code.google.com/p/pharo/issues/detail?id=3714 Stef
