Update tune format files.

In the main one, just remove a couple of now deprecated settings that
did nothing anyway.

For the web format, which is actually the format used to generate
the downloadable PDFs, bring it into line with the main format
but leave the margins at the default settings. Also remove the
deprecated settings.
