Store chapters, merge chapter lists, diff and apply rules

The SQLite store keeps every chapter revision, so a chapter that the site
removes stays in the book. The merge puts new chapters after the chapter
that comes before them on the site. Diffs compare text, not HTML, and
replacement rules run on chapter HTML when a book is built.
