Tons of changes for v0.3.0

Changed CG height, moved graphics offset and colliders to compensate, slightly raised inertia, lowered steering lock, diff preload to 0, clutch max torque to 16, default autoclutch on, added front bumper and nassau panel selections, added sharedData values to support that, slightly widened front with RIM_OFFSET, reverted camber LUT, new tire slip curves, lowered tire damping and spring rate and pressure spring gain to compensate, halved FZ0, tweaked dropoff curve, changed CX_MULT and COMBINED_FACTOR, slightly changed thermals, added nassau panel bouncer, added items to 3D model, took more renders, updated version number
