Hellish Quart pre-alpha v.2025.04.06.0

NEW:
- You can now set the quality of the water shader to "Simple Water" in Options. This might add a few more FPS on "water levels" (1%-5% more - but this might be the difference between 55-57 and a stable 60 fps on low-spec machines, for example)

TWEAK:
- River, Siedliska: Used a faster terrain shader
