beacuse this is meant to be abstracted - c shouldnt be playing with stats of
parts directly. you can talk to the edje via messages - these are used in many
places in e and efl to abstract apis between edje and c code.

use edje messages. battery module does this - exquisite does... done in other
places too! they can pass arbitrary data back and forth.
