Subject: [PATCH] Cocoa: Add missing call to removeObserver:

As noted in the documentation for NSDistributedNotificationCenter,
(under the Discussion heading) before an observer is deallocated a call
should be made to removeObserver: in order to ensure that the listener
is correctly removed from all observation pools.

Fixes #817.
Closes #826.
