      Description

      When fetcher.follow.outlinks.depth is non-zero, fetcher follows outlinks. This patch keeps track of already fetched URL's and thus avoid fetching the same URL twice.

      A Set is used to keep track of them, hashcodes to reduce memory usage. This is not used if fetcher doesn't follow outlinks.
