0.3.4 Further optimization and some roads fixing — Titan Chaser Steam update #315498

In this update: I optimized rendering a little bit more, around main roads with lampposts and Woodville polygon count should be reduced by 20-30% (probably about 5-10 FPS gain depending on your computer) Road exit after a main bridge is more visible now and roads are actually connected. I might use this technique for other road connections A few places on the secondary roads where car would stuck sometimes now should be smoother Pavements have been added in various places in Woodville where the road would be in the air above the environment
