cocoa: Use the close method to hide a miniaturized window

The 'orderOut' method has no effect on miniaturized windows, so 'close' must be used to remove the window from the desktop, dock, and window list in this case.

SDL holds a strong reference to the window (oneShot/releasedWhenClosed are 'NO'), and calling 'close' doesn't send a 'windowShouldClose' message, so it's safe to use for this purpose as nothing is implicitly released.
