Cole Robinson 6043a88a0c snapshots: Add some specific UI for external snapshots
We sort them separately in the snapshot list, explicitly mention that
they are 'external', and add a UI field listing the memory/disk
details.

In general mixing internal and external snapshots is a recipe for
confusion and disaster, so I think the best thing to do is at least
acknowledge their presence in the UI but not make any attempt to
predict what will or will not work.
