[9-dev] RFR(XS): 8088809: MenuItem.setText() is broken (Mac)

[Morris Meyer]

Kevin, David and David,

Please review this small patch for changing a Mac system menu item, 
where that item is a top level menu in the [NSApp mainMenu] menu bar.

The fix is to look specifically in the main menu for these items, and to 
use the appropriate mechanism to set the title of that top-level menu.

Thanks,
