[RE-wrenches] Off-grid e-gauge system

[Chris Mason]

William,
I converted the generator to autostart and added an alert, so you can see
how the egauge sends an alert when the generator is started by the Outback.
The alerts are very useful, especially if the location is remote and not
inhabited.
Let me know if there is anything else you need.
