FS#409 - Batt. level + remaining time est.

The battery level was calculated in a very simple way: linear
interpolation between the BATTERY_EMPTY and
BATTERY_FULL voltage, no matter if the charger (recorder) was
on or off.

my improvements in detail:

- The battery
level (percentage) is more realistic and considers if the charger is
on.
- It considers the “lazyness” a battery shows when the
charging has just turned on or off (see below). But this is not perfect
by now.
- The battery level is good enough to estimate the
remaining running time and the remaining charging time. And so
the info screen now shows this info.
- The maximum time of a
charging cycle is now dynamically calculated out of the battery
level (percentage) and is not a fixed value.
- A minimum of 60
Minutes is waited after a charging cycle stops before another one
starts.
- Added another screen in the battery debug screen
(press down three times).
