StartListening()

void SfxListener::StartListening	(	SfxBroadcaster &	rBroadcaster,
		DuplicateHandling	eDuplicateHanding = DuplicateHandling::Unexpected
	)

Registers a specific SfxBroadcaster.

Some code uses duplicates as a kind of ref-counting thing i.e. they add and remove listeners on different code paths, and they only really stop listening when the last EndListening() is called.
