revised solenoid triggering: it behaves more like an IBM Beamspring solenoid now

* It is deactivated after a short while, so the state of the solenoid does
  not correspond with the state of the key.
* The MCU now less frequently crashes, but quite possibly we will need a separate
  power supply to use the solenoid.
