an eventually opened menu is now quit in BWindow::DispatchMessage()

before sending a B_MOUSE_DOWN message to any other view. This fixes bug 
594 for real and another bug in BMenuBar.  BMenuBar tracking will also 
be simplified a bit because of this. Install items to a NULL window on 
Show() as does R5 (although I don't know why yet).
