crash - function in master that is called in the event the driver crashes
void crash( string crash_message, object command_giver, object current_object );
The driver calls crash() in master in the event that the driver crashes (segmentation fault, bus error, etc). This function offers a way to shutdown the mudlib (safe players and other important data) before the driver crashes. It also lets you log various useful information such as what signal crashed the driver, what object was active, who the cur‐ rent player was etc.
