Summary0000002: StaffAddAboveActionGUITest execution is hanging somtimes
DescriptionStaffAddAboveActionGUITest execution is hanging sporadically. There also might be an exception about concurrent changes. Something with synchronize?

This dosen't happen with other tests nor with the manual run.

As a result builds on jenkins also may hang.

There might be two problems:
1) Caret is blinking and redrawing the whole page in any moment, it could be after the new staff and bracket have already been added but recalculate() is not yet called;
2) Undo/Redo actions enablement is updated before recalculate is done but it calls repaint!

Both mentioned above are fixed, so there is some third reason which calls repaint before recalculation is done.

Solution: synchronize paint and commands (including recalculation and other changes). Put commands to the thread, add lock in the document, let command thread wait until paint thread finish and let paint thread wait until command thread finish.

Fixed in build #145 by synchronizing all document operations.
