Experimental QD32 I4 Diesel for D-Series & Roamer 1.3

-Now works with Roamer
-Added a Non Turbo QD32 N/A (Naturally Aspirated): Much slower version but got plenty of torque for Hauling.. Somewhere around 100-120hp/220nm Torque

Changed engine model from v8 to i6..

I tried using hopper i4 engine model but i'm having problem exhaust/headers.. So i6 for now until some modder allows me use their engine model.
