[BLUEJ-1025] About Dialog appears behind editor
If you are in the main window and go to BlueJ->About BlueJ menu (Mac), the about dialog correctly appears in front of the main window. But if you are in the editor, with the editor menu in front of the main window and do the same, the about dialog appears in front of the main window but behind the editor menu. So it can look like the menu item did nothing.
Also: it's possible to open multiple about dialogs, but there's no use for this, so we should probably make sure only one is shown at a time.
