by including the new snapshotselector. If a whole media-set is to be
restored, select all snapshots
to achieve this, we drop the 'restoreid' and 'datastores' properties
for the restore window, and replace them by a 'prefilter' object
(with 'store' and 'snapshot' properties)
to be able to show the snapshots, we now have to always load the
content of that media-set, so drop the short-circuit if we have
the datastores already.
change the layout of the restore window into a two-step window
so that the first tab is the selection what to restore, and on the
second tab the user chooses where to restore (drive, datastore, etc.)
