Treat the tune title as a paragraph (ragged right). Set the column widths to give
a wider and hence larger first line tune graphic.
Keep using the cropped first line graphic, and introduce our own gaps between lines
to keep the tune separations clear. I did look at using the grpahics borders, but that
gives left and right margins too.
1. Purple background on the front and and new blank back pages.
2. UK English for hyphenation and date presentation.
3. Dedication and 'About Havoc' section.
4. Footer just page number in centre of page.
5. Revised copyright discussion.
6. Since it's a book, make content, intro and first lines to chapters.
And prompt individual tunes to sections.
7. Omit 'Tunes' chapter heading. It doesn't look good in A5.
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.
