Manager: improve error message when unable to create UPnP/SSDP server

Browse Source 
Rather than just print the error message ("error creating UPnP/SSDP
server"), it now explains what the effect is of this error (workers
unable to automatically find this Manager) and how to solve it (pass
`-manager URL` to the Worker).
