[Ovmsdev] Power usage / sleep mode

[Michael Balzer]

Mark, Tom,

I just checked in the auto calibration implementation.

It works by taking the maximum voltage reading while the car is off and 
not charging as the reference voltage, so it should adapt to all 
possible variations.

Alert is triggered if current reading is at/below ref - 1.3V, which 
should fit for all cases.

The alert now also includes the reference, and it can be queried by the 
"DIAG" SMS command. It's also now included as a new field in the 
environment message ("D").

Regards,
Michael
