When listing snapshots in the admin (#12), the snapshots should be shown with a given name to easily identify what is contained in the snapshot (this would be beyond any settings listed below the snapshot when expanded, as mentioned in #18).

In addition to a name, we could make use of the post_excerpt to capture a “commit message” for a given snapshot.

Alternatively, we could just use the post title as the commit message and not have a separate name field at all.
