instead of showing the snapshots directly under the pool and then the
media-sets, list the media-sets under the pool and only after the
snapshots
this has several advantages:
* we only have to read one set of tape catalog data on expand and not all of
them everytime (which does not scale)
* we can show media-sets without snapshots, this can happen when we
inventoried a set of tapes from another pbs instance, or lost the
catalog data somehow
the disadvantage is that one has to go look for the media set where the
snapshot is included, but we can solve this by implementing a search
function in the future (in the backend)
