SnowHard Shader

* Added a new "Ultra" graphics option to the water tab. And added a ripple effect to the water between medium and Ultra quality. (However, it was only supposed to work on Ultra settings; I'll try to fix that in future updates.) * Removed graphical options from the Shader that were not working, such as shadows and clouds. * Increased levels of occlusion and saturation. * Other minor and practically imperceptible things.
