+- alpha02: The session editing form now uses tabs for better structure.
 - alpha01: A MQTT `fop/config` message is published on startup and when platforms are edited or deleted.  Device management applications can listen to this message to display the available platforms.
 - alpha00: Prevent countdown interruptions.  In order to switch from a countdown to a different type of break, it is now necessary to explicitly stop the break using the "Pause" dialog.   Jury buttons for technical breaks are therefore ignored. Ceremonies (Introduction, Medals) are fine since they do not interrupt the countdown.
 - alpha00: Referee decision updates are ignored once the decision has been shown.  Referees must use flags after 3 seconds. In this way, what the jury sees matches what was seen by the public.
