MusicXML export: quarter tones need alter element too
Revisions 2645 and 2649 add preliminary support for quarter tones
However Michael writes :
"Please be sure to add the alter element as well as the accidental element - for instance, 0.5 for quarter-sharp, 1.5 for three-quarters-sharp, -0.5 for quarter-flat, and -1.5 for three-quarters-flat. Please let me know if that still does not work for import into Finale (I don't know if Sibelius supports this during import)."
