Title: Add simple quick update support to installer

Requested in https://github.com/OpenELEC/OpenELEC.tv/issues/202
How this works: tries to mount the System partition by label
If succeeds, checks the mounted filesystem has KERNEL and SYSTEM files and copies them over.
Done.

Possible todo: if mount by label fails, present a list of partitions. But I don't think this is necessary, because if the System filesystem does not have the correct label, it means this is a custom installation, and we really don't need to support updating it with usb stick.

Other ideas discussed in irc: on installation, if there is a backup.tar.gz on the stick, extract it after installation to Storage. Could also add support for making a backup from Storage to usb stick - will need to check backup is not too big to fit on the stick - maybe prompt to backup only settings&addons if low on space?
