Pulled out HelloNeighbour into its own service, INeighbourService, which may get more functions as we go along. It's a very simple service and service connectors, and it served primarily to establish the design of services that dependent on Scenes and that must always have a local connector. More refactoring coming, as this showed how to do it right.
