Fixed: Change appogiatura groups to y

Note that the Verovio code remains the same so that the examples render correctly. This will be addressed in #89. Fixes #113

+                    characters were used to start a group. It also meant that
+                    parsing the code was a bit more difficult, since it created
+                    ambiguities between a single `q`, or a single appogiatura
+                    notes, or a group of notes.
