bat: expose information on battery wear and tear
Modern batteries should expose information about their design capacity which we can compare to current capacity and deduce how much 'wear' the battery got and expose that as a negative value percentage. Feature sent in August took a while to convince the maintainer many modern batteries provide this information. Signed-off-by: Adrian C. (anrxc) <anrxc@sysphere.org>
