Media query fun

I think it's fairly safe to say that we won't keep the stylesheets separate like this due to the insane amount of http requests, but during development — and really for ease of understanding — Ben and I are separating out the media queries, using min-width as a constant (rather than a confusing mix of min and max) and working from the mobile view upwards. The whole layout is fluid, but media queries help to kick certain things into place at appropriate points.
