move battery fetching/polling of info to its own sub process, pipe of stdout

to read like tempget. this means e cant hang hen polling - much better for
the mainloop. also clean up the code a lot. all battery specific "driver"
code is now in batget - this means it much nicer to later add hal battery
info fetching as that is also a remote service (and just not execute batget).
i also fixed up (in theory) the new 2.6.24+ /sys/class/power_supply parsing
to i think work better in more situations. i'm testing on a device i have
that does it - let me know if its wrong...
