    tiling: Reset maximized tile mode when unmaximizing
    
    Maximized tiled windows end up with an inconsistent tile mode when
    unmaximized by other means than dragging the window free (e.g.
    using the unmaximize button or double clicking the title bar), so
    reset the tile mode when unmaximizing.
    
    This is not a problem for side-by-side tiling, as there are no
    alternatives to dragging the window free.
