[Implemented] Ogre3D light attenuation

[dllfreak2001]

For nice 3D-games you need to set the lighting range.

That´s my feature request and i think it´s a realy basic function.

I confirm the importance of this function. I would like to see that implemented, too. It is relevant if you want to create games which need to create some atmosphere or use lightning in a more advanced way.
