* Changed skysphere algorithm to make the skysphere fog adapt to camera height. The lower the camera is the higher up the fog in the skysphere will draw. This has been done to counteract the sky being clearly visible behind fogged peaks. This is kind of a hacky replacement to volumetric fog, in other words.

* Removed a bunch of unnecessary variable sending to different shader files. I dont need to send camera farclip anymore, that gets loaded in directly from the settings file.
