A job placed each new chapter with the chapter order from its start, so
a move by hand during the job went back. The store now places a new
chapter against the order that the story has at that moment, in one
transaction. A recheck of a chapter that the user deleted no longer
stops the job.
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.
