Implementation of undo functions.
The undo system requires calling startUndo() when starting a GUI command
and calling endUndo() when ending the command. All changes to a score
in response to a GUI command must be undoable/redoable by executing
a sequence of low-level undo operations. This sequence is built by the code
handling the command, by calling one or more undoOp()'s
between startUndo() and endUndo().
