Introduce mechanism for having different tune images for compact printed output. Sort alternate .abc in subdir 'Compact' under the booke dir. Use that as the graphic for A5 output, assuming it will be vertically more compact. Use Bear Dance as an example, as it has commentary that currently overflows an A5 landscape page. For the moment, transposed Bookes don't transpose and so don't use Compact.
