A few new changes to the site -

• user refs like @kenny and bare links like https://golangnews.com are now automatically linked in comments and story text

• A reader count (active last 5 minutes) in the header on the home page

• The site is now a standalone process, using a letsencrypt cert (autocert usage coming soon), so it no longer sits behind a proxy

• The site now uses a separate db server, so that I can host the go process as a service on a CoreOS instance (for auto-updates)
