0032612: Data Exchange, RWGltf_CafReader - lost hierarchy of two nested compounds RWGltf_GltfJsonParser::gltfParseSceneNode() - prevent flattering of Scene nodes (allow flattering only of Mesh nodes). Added command XAutoNaming managing XCAFDoc_ShapeTool::SetAutoNaming(). Added comparisons with reference Xdump data to glTF tests.
