In playback, appoggiaturas shift following note rather than subtracting from it
This applies to all MuseScore versions since at least 0.9.5 and to both Windows (XP) and Linux (Ubuntu).
Issue: during playback, when an appoggiatura is found, its duration is inserted before the main note; so that the total duration of the pair is: duration of appoggiatura + duration of main note.
Expected behaviour: the duration of the appoggiatura is subtracted from the duration of the main note, so the total duration of the pair is equal to the nominal duration of the main note.
STR: load and play the attached (silly!!!) score; the notes preceded by appoggiaturas will 'overflow' into the following pause or note.
