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'

and it will be loaded at boot

some minimal error checking is performed prior to using the values

added manual entry

@ -61,3 +61,20 @@ As \setting{Battery Benchmark} needs to write the data held in memory to
disk in order to save them, it is possible that should Rockbox shut down
due to low battery then there will not be enough power remaining to write the
data to disk. Therefore all measurements since the previous save will be lost.
\subsubsection{Advanced}
On first run \setting{Battery Benchmark} will export the default battery tables
to '/.rockbox/battery\_levels.default'
You can use the values recorded by \setting{Battery Benchmark}
to more accurately reflect the capacity of your individual battery.
Once you have made your changes rename '.default' to '.cfg' and your custom
battery table will be loaded next boot.
\note{\setting{WARNING} be aware 'shutoff' and 'disksafe' levels are to protect your player
both over-discharge of the battery and to prevent dataloss.
Setting these values incorrectly may cause damage to your \dap{}, battery, data, or disk.
However, 'discharge' and 'charge' tables are only used to calibrate the battery
meter and should be safe to change to any value.
Each entry should be greater or equal to 'shutdown' and or the previous table entry
otherwise the battery tables will be rejected.
