Big conversion to Marionette.js app

* Includes dynamic fetching of last several youtube videos
* Includes dynamic fetching of the upcoming meetups
* Includes basic responsive grid support
* Includes a css reset via normalize.css
* Includes javascript templates via Handlebars
* For now, the marionette.js version of the site is NOT on
  index.html, but rather served via marionette.html. If'
  we like it we can mv the markup onto index.html
