Review request for Plasma, Sebastian Kügler and Christopher Blauvelt.


Summary
-------

This patch fixes a missing update specifically for the "Free Space" key for the data associated with the source of the StorageVolume. I don't know if the missing update is due to the recent changes in Plasma::DataEngine but this patch seems to solve the problem I've pointed out in the "free space indicator patch" (http://reviewboard.kde.org/r/632/#review2065). As from the docs there's no need to call scheduleSourcesUpdate() when using DataEngine::setData, but i found the need to call updateAllSources in order to correctly update the "Free Space" data.
