Message:

Channels and Notifications pass on subjectKilled().

• if we only sign on to a single notification channel, we miss on subjectKilled() completely. Hence, we have to chance of properly signing off again or, at least, to know that we must not anymore.
• Hence, Observable's dstor now calls subjectKilled() on its Channels which passes the call on to all its Notifications that in turn use the subjectKilled() slot of their targets along with the passed-through Observable instance.
• also added observerLog verbosity when signing on/off to channels.
• explained this in header documentation of Observable, Channels, and Notification.
• TESTFIX: ObserverUnitTest did not properly signOff() before deleting instances in relayNotificationTest().
