Collision avoidance subdivision planes

This initiative is about the dialog in 'Configure Collision Avoidance, Collision Object Properties, Convex Hull, Subdivision planes'

After closing and re-opening the Collision Avoidance configuring dialog all the defined subdivision planes disappear and the process of setting them up must be started from scratch. The defined planes should definitely stay in the list even if the CA configuration tab is closed.

Generally speaking, using subdivision planes is a bit clumsy way of refining the model. I suppose there is a good reason to do it like this. Hopefully it'll get easier in the future. Anyways, Collision Avoidance is a great feature and highly appreciated!

Kind regards,
