Reworked distant emissives

First of all, sorry for another delay, update is coming soon. It’s just that I wanted to tweak distant emissives a bit so they would work better, current version looks way too sad, and it took a bit longer than I originally planned. 

Newer implementation now has separate small point with somewhat constant on-screen size, and larger glow which fully depends on fog, and is completely hidden in clear weather. Plus, that glow is visible further in fog, so it adds a nice backlit-like effect. And also, Extra FX got a new effect for blurring background in fog, just a bit. That  silhouettes  sharpness looks a bit off, I think.

Thank you for all of your support! In attachments, a couple of screenshots with misty weather.
