[Denemo-devel] Major change to drawing

[Richard Shann]

I have made a significant structural change to the code, moving all the
widgets associated with drawing the score and scrolling it out of the
tabbed pages which hold the scores that you have loaded. There is now a
single set of these widgets, which is more natural, and represents a
better way of fixing the bug that Nils found when calling NewWindow from
a script.
Plenty of scope for new problems to show up, but this was a much needed
clean up.
