Removed squid purge in generateAndSaveThumb()

* This is only useful for fixing thumbnails by manually making
  a thumb.php (non cache-handled) URL. This is what ?action=purge
  is for. The only edge case is when the thumb listings are out
  of sync with CDN, in which case ?action=purge does not work.
