v1.4 - Lighting revamp

• Added ThiccWater to itch, previously only available on Gumroad
• Updated lighting functions
• Updated depth maps for less noisy joins, smoother reflections
• Added a white stream emitter because why not
• Created new material slots (71 and 72) to avoid conflicts with older versions.

If you're updating from a previous version of ThiccWater, be sure to run the installer to get the latest materials. All settings from previous installs should carry over automatically, just gotta click the install button.
