Loader.createMaterial: Unsupported colorAmbient and mapAmbient errors

Version: THREE.WebGLRenderer 73
Windows 7, Firefox 44.0

I'm getting those errors in console log:

The zip file (http://warriots.com/allinfo.zip) contain:
folder Chamber Of Secrets (file to be transformed to .json file)
obj2json.py: transformer downloaded from this repo a few hours ago
index.html: file with the html and js content
escena.json: JSON file to be rendered. Output of the chamber of secret.obj file.

Why Chamber of secret? Well... I just downloaded an example from the web...
Probably that is the issue... Some old 3dMax version. I really don't know.
Here the file: http://tf3dm.com/3d-model/chamber-of-secrets-scene-45247.html

If you don't feel confident opening that .zip file, let me know and I could send you all files with no .zip file

It might happen because ambient was removed from material from r71.
You can read that in the release notes here.

@mrdoob I've seen in dev, that THREE.Loader.createMaterial produces a warning for colorAmbient(see below), but not for mapAmbient. Do you think, we should add mapAmbient in the same way like colorAmbient (so users get a warning and not an error)?

case 'colorAmbient':
    console.warn( 'THREE.Loader.createMaterial: colorAmbient is no longer supported' );
    break;

@Mugen87 nice catch!
