Allow Script Engines like CTLD to Add Cargo Weight to Helicopters

[Hawkeye91]

Currently in most MP maps, loading troops/cargo doesn't impose any weight on the aircraft. Dynamic severs use these logistics scripts for support helicopters. While I enjoy the logistic shlepping across the map in a slow mower, I'd like the added realism of the weight on the aircraft of what ever it is I'm hauling. Thanks everyone at ED.
