Problem reported by Stefan - user presses the "stop the run" button, and the web page comes back saying "running" as if the button did not work. This is 
confusing. It happens because mtransition did not start yet - we have a race condition against it.

To improve this situation, mhttpd now remembers that a start/stop button was pushed and displays a message "Run start/stop requested" until it detects 
that mtransition started and set "runinfo/transition in progress" (or the run state changed).
