Headlights v1.0

Changed colors, foci, and ranges for stock trucks' headlights.

These headlights (low & high beams) are game friendly, but not realistic because they illuminate more of the road ahead than real-life headlights: they do make in-game night driving easier).

Compared to stock headlights . . .
- Low beams are wider close to the front of the truck so turning at intersections at night on country roads is easier (this feature IS like real life).
- Both low and high beams have higher color temperatures (less yellow, more white, but not blue).
- Low beams virtually eliminate bloom (making speed-limit signs readable) even when HDR is enabled; high beams still wash out signs as they approach.

This mod does not affect accessory lights.

Tested in ETS2 v1.28.1.3s 64bit
