Refs #3332
 * Transition works for Page titles with hierarchy (eg "$Category / $name")
 * URL metadata:
  * is only available on non Summary rows.
  * It is now set to the page with highest number of visits, when page names do overwrite.
 * However now, by default we do track keep hash tags and we do not aggregate them in one page URL.
  * Refs #3232 Will be nice to have, to allow to "not track fragment" by default. See stub processUrlFragment().
    More to do: Admin UI, Tests w/ and wo/ hash tags, w/ Capital letter in hostname
  * URL being tracked, and URL read from the logs (for backward compatibility) are now cleaned: hostname is lowered,
    and URL Fragment is kept/removed.
