Re: [Denemo-devel] Breve and Denemo's understanding of durations greater

Compiled from current git. 
It looks like SetDurationInTicks works fine now.

Except that all normal Denemo notes get a whole-note shape afterwards. If we 
think of doing tuplets with SetDurationInTicks this could be confusing :)

Good work! A whole new branch of scripting options came up because of this.
