Add support for 3DObject.

Use one of the three shapes for the collider, box, cylinder or sphere. Original orientation of the model may require changing for the cylinder alignment, it expects Y axis to be up.

The size is set on the first render of the model (including animation.)

Also able to override the size through properties.

Additionally, a new ACE to offset the collider (for example to center the Cleric model which has the origin at the feet): Set position offset.
