Finished Automatic Sitemap Generation and Added Link to Footer

As a part of our ongoing efforts to make BlockchainJournal's (BCJ) authoritative, enterprise-targeted content discoverable across various search engines, we activated an automatic sitemap function and added a link to that sitemap in our "perma-footer."  The perma-footer forms the bottom of BCJ's u-clamp; a U-shaped fixed frame of site-wide navigational elements that forms a well through which all of our content can scroll.
