Sacred Harp is broken in minor keys

[Ted Walther]

When the current key is a minor key, the shapeNoteStyles are set wrong.
I don't know how to fix this, but it would be nice if the
\sacredHarpHeads had some knowledge of the current key.

shapeNoteStyles is already set correctly for the major keys.

%major
%sacredHarpHeads = \set shapeNoteStyles = ##(fa #f la fa #f la mi)

%minor
%sacredHarpHeads = \set shapeNoteStyles = ##(la mi fa #f la fa #f)
