Title: A/B test responsive theme

Redirects proved to be problematic for a) speed and b) form posts, so this code uses the Content Experiment API as described in https://developers.google.com/analytics/solutions/experiments-client-side to swap the styleseets to the responsive ones and rewrite the header and footer as the document is written if the responsive arm of the content experiment is selected.
