New MiscObject property (passable)

In OpenSCENARIO 1.0 MiscObject has category and bounding box and it is not easy to interpret within scenario if the object is such that vehicle can pass through/over it or not. Examples of always passable categories are "Wind", "RoadMark", but other times it depends on the setup ("Streetlamp" over the road, "Gantry", "Tree" - with trunk out of road, but canopy over the road). Adding a boolean property would help address the issue.

To be specified: Does the property affect "Collision" condition or not? What would be the default?
