gcode: Attempt to shutdown heaters and fans prior to a RESTART 

If the user requests a restart and the machine appears to be otherwise
functioning normally, then attempt to stop the heaters and fans prior
to restarting the host.  This prevents the firmware from going into a
shutdown state when the heater is on and the host restarts.
