So GPIO 13/ pin 33 is used to toggle the power.   We could use the
python scripts to do this, but then we need to install python.......

I'm thinking that SqueezeButtonPi Daemon would be perfectly suited for
this.  It already is setup for monitoring GPIO and could be easily
modified to launch a shutdown command.   I'll have to look into this.
