Site redesign, 02/12/2013

Hi Lynn, 

Finally, a pull request! Here is the redesigned site with the new widgets. I spent some time yesterday going back through CSS and making site fully responsive, so it should look pretty good on all form factors.

I have a couple of caveats that I will also post as issues:
* New Twitter api (sucky) rules make it near impossible to test widgets in a dev environment, so I can't promise that the Twitter widget will work/look right. I will keep on it if it doesn't.
* I would much prefer a programmatic way to bring in the latest two blog posts on the homepage, but since I couldn't seem to make Mynt cooperate, I hacked media queries to show the latest two at different screen sizes. This will only work for the time being because the size of the blog post excerpts will change, causing the second post to be cut off at some weird point. Maybe someone with better Mynt skills than I can figure out how this could be achieved programmatically? 

Anyway, thanks for being such a rock star and handling all this stuff!
