Chopped Corn Flow - realistic corn discharge for every combine.

In the base game most combines show little or no chopped corn leaving the chopper while harvesting corn. This mod makes chopped corn visibly fly out of the chopper, the way it already does on a few machines.

What it does:
- Makes the central chopper effect on all combines show visible chopped corn
- Works with base-game combines and with combines from other mods
- Changes only the visual effect: no gameplay, yields, prices or savegame data are touched
