[Ovmsdev] Time for release 3.2.016?

I found the reason for the false theft/flatbed alert in my case by 
checking my telemetry archive: the car lost GPS on the road. Coordinates 
were stale when I parked the car. The stale coordinates were taken as 
the initial park coordinates, causing an alert when the GPS receiver 
delivered the next valid data (the actual park position).

So the bad antenna placement actually was the cause in my case, but we 
can solve that in software.

I've just pushed a fix (untested) for this, consisting of a) making the 
location module aware of parking coordinate staleness and b) lowering 
the staleness thresholds for the GPS metrics to 10 seconds.

Please verify.
