Added Foundation 3 for IE 8 and older, added workaround for home full-page background
Added IE-specific CSS file, removed full-page image background fallback
Did a LOT of changes - added a JS fallback for allowing media queries on IE7 and 8, added some PNGs of used SVG assets (and added their fallbacks into main.js as well), and overall improved the general layout of the site on IE8.
