timer: Add ringing and counter

The timer app issues a short buzz once and then disappears. There is no
trace left that the timer finished or how long ago. This change makes
the motor start ringing and presents a timer counter.

The timer stops buzzing after 10 seconds, and finally resets after
1 minute.
