Potato Shaders Preview E3

Oi, this pack also got some updates today:

- added fog settings
- added image sharpening
- added film grain
- added underwater refraction
- added in-lava fog

I'll most likely try to come up with something create for the end dimension next and feel free to lemme know whatever you might want to see in this pack as well, but keep it reasonable since I aim to make this as lightweight as possible :)
