adds wetness

cliffsnotes:
   $Core::WetnessTexture = "core/rendering/images/wetMap.png"; //for the influence degree map
probes/skylight have a new canDamp boolean, set to off for probes, on for skylight by default.
:levelinfo has a dampness multiplier (0-1)
kicked up numTextures from 8 to 16 for shaderdata and postfx since that hit the 8 texture-in prior limit, and we've already adopted apis that can handle the higher count
