Fix CHANGELOG: restore accurate 0.1.0 entry, add inline boolean note

- 0.1.0 entry: restore nb_scenarios description (that is what was shipped
  in 0.1.0; the playlist feature is in [Unreleased])
- [Unreleased] other-changes bullet: broaden boolean rejection note to
  cover both inline include/exclude lists and JSON playlist files
