David Robillard 332a3d9813 Selection of visible note range (full range vs fit contents, selectable from midi track menu). 
Added note pencil tool, mock note adding (notes can be added visually but don't yet play).
Reworked MidiModel to be notes w/ duration instead of realtime style MIDI events.
Moved layering (stacked/overlaid) from auto time axis down to route time axis since it applies
to MIDI tracks as well.
