Identity: unquoted names are no counters; renumbered and timestamped image sets

- The file total is read from the subject without the file name, as with a
  quoted one: "shyla-shy-09-0195.jpg hardcore …" read as 9 of 195 made each
  of 866 images a release of its own.
- imageSet: "_N" right after a number is a renumbering ("kate108lg029_28"
  once an image was skipped), and a trailing camera timestamp
  ("kurozo-2006-7-26-15-21") numbers no set.
