Shutdown after print finished

[DeltaCon]

I have implemented a PS_ON/OFF relay last week. I read that most users tell their slicers to add power up and down commands to the gcode. I was thinking about how handy it would be to do this from DWC. 2 checkboxes:

V - auto power up on start of print
V - auto power down on end of print, but wait until after heater has been cooled to <50

Sometimes you don't want to power down, because you know you want to start a new print.
Sometimes it is ideal to have the printer auto-shutdown because of course you are not printing unattended, but you might be somewhere else in the house

A solution might be an optional parameter on the M81 command that means "defer the shutdown until the print has finished and the extruder heaters are cool".

Yes, I guess that would be nicer for PanelDue users indeed.
Point is, I would rather decide from the print-start whether I would like to shut down afterwards, and not already from the slicer setting.
