Cron config hierarchy

Hi -

When nested configs are run from cron, the child can get called before the parent - so the child config's files are missing. I think cron needs to honour the hierarchy, and it seems the easiest way to fix this is to change media_mover_api_get_configurations() so it orders by parent - patch for this is attached. It is a commonly used function though - but I've tested and so far haven't found any repercussions for updating the order..?

Cheers,

Ben
