Status bar: Battery color and animation, (1/2):

- Show/hide percentage text
- Enable/disable charging animation
- Custom battery color
- Custom percentage text color

If battery status is below 16 percent, the battery and percentage text color
is "fff4511e", (deep orange 600, Android default).

The charging bolt will only be shown, if percentage text is disabled, or animation is disabled,
otherwise the percentage text will be shown.
