Initial support for the X3D scene file format (see http://www.web3d.org/).

For now, just mesh import. Supports all geometry nodes in Rendering, Geometry3D, CAD geometry modules. No support for materials, color, or textures. Normals in the file (if any) are ignored. Light sources, viewpoints, sensors, world, shaders, scripts also ignored.
