Title: Exit early if picture is natively supported. Also make use of Modernizr if present (not required)

Ok, here's the modification as promised. I've added the Modernizr test too, since it just takes a few lines to look for Modernizr and add the test if it's present. Additionally, media queries will fall back on Modernizr.mq if present. The Modernizr stuff is optional and easy to remove if you feel strongly about it.
