After reconnection, or on manuall opening the app, the watch user can get the phone to make a sound to help locate it.
The way the app is now more context sensitive, with different presentations for initial splash screen, manually started, and when started by the worker process because the connection is down, or has been re-established after being down.
This is the first release. It's functional on my watch, but since I've had no feedback I'll call it a beta version.
It could be prettier, and I expect to add a feature or two yet.
