FCPClientReferenceImplementation: Implement new notification handlers
FCPClientReferenceImplementation: Wire in new FCP message handlers
FCPClientReferenceImplementation.FCPParser: Rename

- The old name "FCPParser" sounded like it would parse *all* FCP
messages, which it does not. There is parsing code in the various
FCPMessageHandler child classes as well.
- Its a good idea to rename it to FCPObjectChangedNotificationParser
since the parseSynchronization() will soon be removed as
synchronizations are currently changed to work differently; after that
has been removed its only parsing will be of the
ObjectChangedNotification.
