ObjectLoader: missing class member crossOrigin

[MarcelKlammer]

Description of the problem

ObjectLoader has no class member crossOrigin, only the method setCrossOrigin is present.

Comparing it to other classes like TextureLoader, which has

crossOrigin: 'Anonymous'

ObjectLoader should also have this member specified.

I tried to have a real S3 URL in images in a json file instead of data:

The following error occured:
THREE.WebGLState: DOMException: Failed to execute 'texImage2D' on 'WebGLRenderingContext': The image element contains cross-origin data, and may not be loaded.

This error is gone when adding

crossOrigin: 'Anonymous'

as a class member to ObjectLoader.

It's maybe a good idea to add the property to ObjectLoader and JSONLoader. The latter one does not even have the method setCrossOrigin().

Yeah, I think we should harmonize this.
