More foggy fog  

This makes the foggy weather have really dense, low visibility fog. This is just visual, NPCs will ignore it for now.

Update 1.1:
-fixed lots of skybox/ lighting issues for foggy_1 since the original file wasn't made for dense fog.

Update 1.2:
-added an option to make the fog distance in foggy_1 the same as in foggy_2, the skyboxes are still different.

Update 1.3:

-fixed a wrong value in Option 2, at 5pm the fog was way too dense

The mod only consits of 2 files, if you want to keep one of the normal foggy settings, only install one of both files.
