Auto updates

[Skywatch]

Yesterday I put one Xbian pi on auto update.
It seems to be working, although the required reboot to fix the upgrades was not done and no message appeared to prompt the user until I went xbian-config->updates->check for upgrade. After that check it said all was up-to-date but that a reboot was needed. I don't know if this is expected behaviour or not, but just thought I'd let you know!
