COMMENTED ISSUE: option to export selected items as separate modelvisual3d

We should have an option export selected objects in blender as individual modelvisual3d objects within the same scene. So one doesn't have to reasemmble the whole scene afterwards. This is especially cumbersome if you need to exactly repostion everything the way it was in the blender scene.

Of course one could export the whole thing as one big modelvisual3d with lots of seperate geometrymodel3d but this is often not desired e.g. when you want to be able to click individual objets.
