When we place a shape, pick a plane.

We may base this choice on context, for now pick the "ground" based on the 3D cursor's dominant plane pointing down relative to the view.

Warning

Calling redo from property updates is not great. This is needed because changing the RNA doesn't cause a redo and we're not using operator UI which does just this.
