* clean up CLightEnv a bit

* add CLightEnv::m_TerrainShadowTransparency * shadows will let a fraction of diffuse light through * added JS LightEnv objects, so the lighting environment can be changed from the console * new element TerrainShadowTransparency supported in the scenario .xml format, changed cantabrian_generated with an example This was SVN commit r3513.
