Change all change notes to reference the filename of the tune to change to.
Modify web and document generators to pull the change note out of the abc
and generate an appropiate bit of content. This is now, in both cases,
a hyperlink.
In the process, remove the tune-specific .tex facility. It wasn't being
used.
I could really do with a proper templating system, and using some sort
of templating in the LaTeX generation.
The old image had joins when it repeated. RReplace with a bitmap
of colour 8000ba with GIMP Aristic/Clothify filter applied with
Blur X/Y 20 and depth 1.
Move text to 5px margin, which combined with the 5px margin specified
in the banner CSS gives a 10px margin for text, matching the content.
Give buzzard more of a vertical margin.
The previous bitmap had green tinges around the main wording. And I wanted
to have 'Cry Havoc Botley Morris' around the buzzard.
Also add the Inkscape SVG used to generate the banner bitmap.
