[FEATURE] EXCUTE GCODE, but ignore failures (e.g. printer is not connected)

[numericOverflow]

Currently, if you execute GCODE as an action, if the printer is offline or not connected, the GCODE fails (as I'd expect) but prevents any other actions from executing.

It be much better to execute the GCODE, but make it OPTIONAL so if it fails, other steps continue.

In my case I have a power relay toggle button. I wanted to home when pressed and the printer turns on. If the printer turns off, I don't care if it doesn't home, just keep doing other stuff in the actions list.
