Theme reskin to match new boundless site

We have been tasked with reskinning the current workshops site to match the new Boundless (previously OpenGeo) website design (which can be seen here: http://opengeo.dev.integritystl.com).

We had to completely replace the header and footer HTML as well as tweak some of the CSS. I did my best to preserve any previous existing scripts and HTML. 

The header and footer links currently match our development site, but will need to be updated to the new live site urls once the Boundless site is launched publicly.

Please feel free to email me at arod@integritystl.com with any questions or concerns.

Thanks!
