commit development & production copies of main stylesheet
rebuild modernizr after removing media query setting
set lynda ad page element to "display:none" so the ad hides on page load
fix typo in js/config.js (missing comma)
add matchMedia() polyfill files to the site build
link matchMedia() polyfill .js files to all site templates...for now (see msg)

link both js/vendor/matchMedia.js and js/vendor/matchMedia.addListener.js to:
- _layouts/categories.html
- _layouts/default.html
- _layouts/post.html

This was done so media query-powered JS functions work in Opera 12 & IE9, but the goal is to get these files working via RequireJS sooner-than-later date.
