[NSE] Added a new httpspider library which is used for recursively crawling web sites for information. New scripts using this functionality include http-backup-finder, http-email-harvest, http-grep, http-open-redirect, and http-unsafe-output-escaping. See http://nmap.org/nsedoc/ or the list later in this file for details on these. [Patrik]

And my web scanner can port scan. It's a strange world.
