Revise scripts for building printed Bookes. A lot of stuff was being duplicated between different page size. Consolidate where possible, and in particular put as much into a single source file (dottes.tex) as possible. Making a single Booke is now potentially quicker, as the tune pages don't necessarily have to be regenerate every time.
