Sepang TreeFX (3D trees) plus more config changes 0.8.2

• Added some fake lights around the track to keep it lit at night, should be able to drive cars without headlights at night now

just small fixes, some objects refused to hide

• I updated the glass on the track to use a newer shader
• finally fixed the line shadows (maybe?)
• changed some lights and shadows to make night racing better

I redid the trees to be closer to the real track, there is more trees now than i can count, it should be over a thousand.
Other Changes:

• fixed lines on main straight and pits having strange shadows from headlights
• changed the lighting to more accurately reflect the modern track(still need to replace some lights manually) night racing should be better though
• added local cubemap for the big glass surfaces so they dont have strange reflections while you drive on straight
• added a ton of track occluders to keep framerate up (might be too aggressive)
• maybe other small things
