App 2.12.1: no scroll bars; energy since start

The pages' scroll bars never faded on the car: a ScrollView shows its
bar on every layout, and the live values lay the page out every two
seconds. StableScrollView, the root of every page, now has none.

A new "Energy since start" tile, left of "Usage since start", shows the
net kWh taken from the pack since the trip began, recuperation counted
back.
