Subject: Finally, merged the improved power code from Uwe Freese:

- 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).
