    Fix fullscreen behaviour
    
    The check in _windowsRestacked checks for
    windows[i].x >= primary.x
    and
    windows[i].x <= primary.x + primary.width
    (likewise for y).
    
    This is wrong because a fullscreen window on the secondary screen is likely
    to have windows[i].x == primary.x + primary.width which means that the checks
    for _both_ screens would be valid, but the first one would win due to
    the "break;" statement.
    
    But here the window isn't really on the primary but on the secondary one.
    
    Fix that by using < instead of <= for those checks.
