A blind fix for Issue 13443. GTK may sends a GdkKeyEvent whose |keyval| is GDK_KP_Tab in pressing shift+tab keys on an X terminal running on Windows. This change just adds GDK_KP_Tab to HandleCustomAccelerator() to handle this event. (This is a blind fix since I don't have any environment that can reproduce this issue.)
