Black Exhaust Smoke v1.0.1.0

This script turns vehicle exhaust smoke black.

Version 1.0.1.0
- Patch 1.4.1 compatible

Version 1.0.0.1
- Exhaust smoke made even darker and more visible

In addition, the transparency (= how much black smoke there is) is influenced by the engine power, i.e. more powerful engines smoke a little more.
In order to keep it realistic, however, the effect is quite weak. If you are looking for a black cloud of smoke, you are in the wrong place.
