This changeset refactors the #removeClass logic (which has been upgraded by Marcel recently) and extracts it to SystemNavigation, analogously to System-ct.1221. It also refines the dialog to search for senders and subclasses of the class to remove as we know it from #removeMessage.

Please merge or give me feedback for improvements. :-)

Best,

Christoph
