Added configuration for computing vertex normals on JSON model loader.

This allows some models to get a much "smoother" look.

What do you think about making a small standalone component? This seems useful, but isn't specific to any one format.

For example something like:

AFRAME.registerComponent('mesh-smooth', {
  init: function () {
    this.el.addEventListener('model-loaded', function (e) {
      e.detail.model.traverse((function (node) {
        if (node.isMesh) node.geometry.computeVertexNormals();
      });
    }
  }
});

... then this would work for any file format, too.

That's a good idea. As part of aframe-extras or a separate repo on my own account?

Up to you! I'd take a PR, probably in the misc folder, or feel free to start a repo. :)

Actually I just ran into a use case for this with a glTF model, too.

Finally got around to this: #165
