Add function moveobject, which currently moves subdisks to different

Browse Source 
drives.  This function just does the low-level configuration changes;
the resultant subdisk is stale if it previously had any contents,
otherwise it is empty (i.e. in need of initializing if it's RAID-5).
We still need to handle getting the contents moved over, but the
current version will suffice to migrate subdisks from a disk which has
failed.
