[Suggestion] Potion Effect and Fog Configs

[Roonas]

A config option to make the player have immunity to darkness when under the effect of night vision to mitigate annoyances when doing something like being in spectator mode with a night vision potion and having your field of view limited. Having to place light sources when the player can already see clearly is an odd and non-intuitive behaviour when you can actually see what is considered dark without use of a light level overlay, and the chance of night vision running out in the dark presents an added layer of danger and complexity, punishing players who don't carry extra torches and blindly run into dark spaces.

Config option to turn off the fog effect, especially when used in tandem with other darkness mods that make the world naturally dark, as it can interfere with your view in an unintended way.
