list_versions

List the model's saved versions, newest first, with number, kind, annotation, author and date. Kinds:

• named versions are kept until someone unpins them. create_version makes these, and publications pin to them.
• auto versions are autosaves; only the newest few are kept.
• rollback versions are made by restoring an older version.

named_count and named_limit show whether another named version still fits.
