    Bug 649993 - Change behavior of --component option
    
    This is primarily for the GNOME Shell calendar.
    
    If, for example, "evolution --component calendar" is invoked and there
    is already an Evolution window opened to the calendar view, present that
    window.  Otherwise open a new Evolution window to the requested view.
    
    Same behavior applies to all requested views.
