when battery_bench is run exports a file in the rockbox directory called 'battery_levels.default' if the user wants their own levels they can rename the file battery_levels.cfg and it will be loaded at boot some minimal error checking is performed prior to using the values added manual entry Change-Id: Ia0126faced0c7229fcf8385a1bcb584b5a9dc378
