[1/3] base: battery light settings

This also adds a new "level" for 100% full battery
to get rid of the comments from people who complain
that 90% is shown as full :)

required overlay:
    <!-- Is the battery LED intrusive? Used to decide if there should be a disable option -->
    <bool name="config_intrusiveBatteryLed">true</bool>

    This will enable if the batter light option is shown in settings

    <!-- Does the battery LED support multiple colors? Used to decide if the user can change the colors -->
    <bool name="config_multiColorBatteryLed">true</bool>

    Also set this for devices like the HTC one which has only
    two colors. This will be handled in the color selction dialog.
    Dont set if for devices like flo which only has white led
