Implement local notification.

Browse Source 
The default behavior is to only notify remote changes, but for some
applications (e.g. GUI's) it's advantageous to know about local
changes as well.

This is (slightly) optimized in that local changes only result in
additional resources being consumed if (any) local listeners have been
created.
