Make output larger where possible. This is done by a) reducing the page margins b) compressing the heading and removing all but Notes: fields. The latter produced vertically smaller tune PDFs that will scale wider. In the process, modify abctitle.py to extract the first of any header field, and move formatting for a single tune into a .fmt file.
