Search and the web interface use the prober's findings

- Search matches a word in the name or the inner name (trigram index on
  inner_name, partial, built concurrently); "Readable names" includes
  releases with an inner name.
- unlocked=1 (chip "No password") leaves out passworded releases.
- Results carry passworded and innerName: a Password badge, the inner
  name under the release name.
- The release view: Inside and Inspected facts, a passworded notice, and
  Contents (per probed article its yEnc name, kind, type, encryption and
  the names inside) from release_inspections.
- Newznab: the password attribute from the prober; an obfuscated release
  with an inner name is included, titled by it (without its extension).
