Identity: other quoted text, text separators, ids in image names, more

- Quoted text other than the file name stays in the remainder: ">>> CREATIVE
  COMMONS NZB <<< "0190 alarm 5.0 " - File 1 of 9: "…rar"" made 12,605
  files of all uploads one release.
- namesRelease accepts words joined by , & : ; \ / + ("Posting & deleting,
  read 0 file "E:\VladModels\y038_Irina\185" …"): such image sets fell to
  the stem rule ("P8250001.JPG"), one release over all folders.
- imageSet: a 5+ digit number left in the set is a per-image id
  ("sss-70556-3474182-23-10825418-pc", "Alena p 26663_…"): no set. Copy
  markers may repeat ("diana-050-052[1][1]").
- unquotedName: an image after numbered text without a separator is the
  last word ("<abm> … AB: part2 0573-1002 043.jpg").
