Improved book structure / fleshed out styles
Web inspector works in book mode now

I crappily modified CSS Regions so it doesn’t convert all styles to
inline. That way you can make tweaks in the inspector without
triggering a slow and painful page regeneration! Text won’t reflow but
you’ll get the general idea.
