    Hack that works around firefox plugin crash
    
    It turns out that mozilla, as per the gtk2xt code selects for input on
    the socket with a mask of 0x0fffff (for god knows why) which includes
    ButtonPressMask, causing a BadAccess if someone else also selects for
    this. As per the client-side windows merge we always normally selects
    for button press so we can emulate it on client side children that
    selects for button press. However, we don't need this for GtkSocket,
    so we unselect it here, fixing the crashes in firefox.
