App 2.10.1: show negative usage while recuperating

Browse Source 
Net regeneration over the window (or the trip) used to hide both
estimates behind "needs a few minutes of driving". It is a real
reading: the usage now shows as negative kWh/100 km, and the range as
"> 999 km" with "while recuperating" beneath it.
