Title: Drop Adelle Sans for Source Sans Pro

I'm proposing we drop Adelle Sans and use Source Sans Pro from Google Web Fonts. Apparently **this shaves 300kb off the docs file size**, a huge win for #354. Plus, rather than `font-weight: 100` everywhere in media queries, we stick to one font weight, no matter the screen.

Visually, they look pretty similar to me, and that page load is huge.
