Cleanup: use free_weightsystem function instead of explicit free

Browse source 
Instead of freeing internal data of the weightsystem structure,
call the free_weightsystem function (which has to be made extern
at first). This makes things more future-proof, should the
weightsystem struct ever be extended.
