Container animation not playing when same container is opened multiple times

[beliar]

When the same animated footlocker is opened multiple times the animation does not play anymore.

This is caused by the call to self.hide_container in create_box_gui in hud.py which itself calls box_container.container.close() which will close the container - but not the gui - thus playing the close animation since the change from the OPENING state to CLOSING state is a valid change.

This can be fixed by adding self.box_container = None at the end of hide_container which means that the code in hide_container will detect that it currently has to box_container and will not execute the close function. I have added a patch to the ticket that does just that.
