Implements a function similar to the PNotifier, but uses an "id" to link the caller and callee rather than using a pointer.
This has the advantage that if the pointer becomes invalid, the caller can gracefully fail the notification rather than simply crashing due to an invalid pointer access.
These classes were created to support of the XMPP classes
