Visual Effects Vol. 1 (#14610)

Browse source 
This PR adds a variety of effects to enhance the visual experience.

    "soft" clouds look
    Tinted shadows
    Crude water reflections (sky and sun) and waves
    Translucent foliage
    Node specular highlights
    Adjusted fog color (more saturated where the fog is lighter)
    Minor changes to volumetric lighting (crudely simulates the effect of depth)
