App 2.10.0: range since start, usage in its own cards

"Range since start" replaces the range at current power: remaining
energy over the consumption since the car was switched on, standing
with the climate on included. A trip starts again after 10 minutes
without samples (the car was off) or when charging.

The kWh/100 km for both estimates moved out of the range tiles into
two cards of their own, directly below them; the overview still fits
the full-screen 1920x720 display without scrolling.
