* Completely removes volumetric lighting effect for the time being... Needs a rewrite to be faster and it si a tad to much for such a blocky game anyhow. :)
* Disables volumetric fog for the time being - shouldn't be a global effect and doesn't look to good either at the moment
* Renames "Local Reflections" to SSR and marks them as an experimental feature
* Fixes that local reflections were always active and thus "overwrote" the costly global reflections
* Adjusts all video/rendering settings accordingly
