Title: Do not dedup thrashers

A couple of new de-duping rules:

* Don't dedup snaps ever (previously we just didn't dedup dream snaps)
* Don't dedup a container that only houses one item. These are typically big image containers, like the eyewitness container, or a thrasher, so we ought not to dedup the only item in them.
