Changed behavior of -watchdog option to act like a real watchdog. It now
specifies the number of seconds after the last video update that will cause auto-termination of MAME. Also modified it to output a message when the watchdog triggers the exit. Updated windows.txt to reflect this option and the debugger_font options which were never previously documented.
