* Added `scene.ambientColor` and `Scene` now ignores `AmbientLights` (transferring hex for temporal backwards compatibility)
* CanvasRenderer and SVGRenderer using `scene.ambientColor`. Tried to update `WebGLRenderer` too, but the method in question doesn't seem to have access to the scene :S
* Removed `scene.origin` and updated examples that used it.
* Improved subdivision example
Found out that CrosseyedWebGLRenderer probably wouldn't work for target-less cameras.
Something weird going on with `webgl_scene_test.html` and `webgl_scene_test_blender.html`. For some reason cubes dissapear.
