The timer's time as received by the server is clarified to be the actual
numerical time, in milliseconds, to be shown on the clock.

Implement clock setting w/o starting or stopping
Both of these should make it possible for the server to start/stop/pause/resume the clock with perfect synchronization to the true time.

Clock can be defined in courtroom_config.ini and its font set in courtroom_fonts.ini
Pause and resume functions will not work as expected atm.
