PCP20: Turtles for Christmas! (Patreon)

Merry Christmas! Have a turtle, or several! Turtle skins are finally done, still working on the turtle shell armor piece and item icons associated with them, but we've also got glowy redstone ores with shaders, and improved blending of all dripstone-related blocks. Regarding the dripstone stuff, the current palette should be viewed as a placeholder, as I plan to make much more detailed palettes based on altitude and individual biomes in the future as I switch to the grid format. Additionally there are plans to blend all stone blocks generated in caves with overlay CTM. No ETA on this yet, as it involves a lot of planning, and mobs and item icons are going to be the number one priority going forward.

Changelog
[1.18b](tentative)

-Added textures with 9 random variants for turtles.
-Added all 6 boat model textures with unique engravings for each and associated item icons. (Finally!)
-Increased animation framecount for all 3 redstone ore textures due to inescapable issues with labPBR.
-Decreased overall saturation for all blocks related to dripstone.
-Added custom biome palette for all blocks related to dripstone, to better blend them in with the environment.
-Removed unused stalactite textures.
-Fixed a bug with turtle eggs not being 64x64 resolution.

---Shader Support---
-Updated shader presets to support BSL_v8.1.01 up to BSL_v8.1.02.5d (zipped and unzipped for easier installation)
-Added animated spec and glow maps to all 3 redstone ore textures so that they now glow in the dark. (bump maps to come later with the rest of ores/stone.)
-Added POM, normals and specular maps to all new boats. (Submerged parts of boats will look wet!)
