GuiNotification: demote this service to be just a BusTerm

in fact it just does not fulfil any of the behavioural properties
of a full-fledged UI-Element. All it needs is an uplink bus connection,
so let's just keep it as that

Sidenote: I've realised today that such a "free standing" BusTerm
without registration in Nexus is a good idea and acceptable solution.
