Rebuilt this site using a static site generator

I'm also in the process of rebuilding this site. Previously all the pages were rendered using ASP.NET MVC with a tag helper that rendered markdown to HTML. As of today the site is now all rendered statically using Gulp, gulp-static-site, and the Jade templating engine. Overall that makes it faster and easier to maintain. Of course the actual demo is still in ASP.NET but it now runs purely as a SignalR hub application.
