Updated to support pulling in stylesheets from the body of the HTML document (tested for IE 7 and 8).  This is achieved by first using IE conditional comments to change the mime type of the <style> tag to an invalid mime type (such as "text/x-OldIEIrritatesMe") so that IE 7 and 8 do not natively process the style tag.  With this in place within the document, Respond.js is able to find and parse style tags in the body of the document.  One future possible change would be to do the same for header stylesheets, as well as change the mime type (and set rel='alternate') for the link tags in the header, eliminating the double file pull for the stylesheets in IE8 and below, allowing Respond.js to pull the file instead.
