FS#13538 export and import battery level tables

Browse source 
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
