GNSS App: a Compass, with Places to be led back to and a level

Tab goes on from the Sky to a third view (issue #16): a rose that turns
with the device, the heading, where north came from and how long ago,
the sun on the rose, and a level. m marks where you stand as a Place,
t picks one as the target: an arrowhead on the rose, its distance and
bearing. The sensor's directions were checked by hand on the device.
