Title: useAlphaFromDiffuseTexture option for standard material

enable this option on a standard material make the shader algorithm use the alpha channel on the diffuse texture.

This avoid aliasing effect on transparent textures. See example [demo](http://arthur-brongniart.fr/Stockage/BABYLON%20useAlphaFromDiffuseTexture/demo.html)
