Added /book-static/ so we can play with css better

Rather than regenerate the book, which takes a few minutes, you can
visit localhost:4000/book-static/ to see css changes. It’s a static
copy of all the pages, so it won’t reflow if you change the type size.
I’ll update /book-static/ manually when we make any significant
template or content changes.
