v0.4.0-alpha

This is a quite major update with new features, both physical and graphical. The physics have been completely rethought in some areas and generally improved all-around while trying to stick to realistic values and to match telemetry data.

Changelog:

• Added ROK Shifter class
• Added new visual options: metal sidepods, metal rear bumpers, vintage nosecone and plate, and a retro/vintage style steering wheel
• Added stuff to the 3D model (airbox, carburetor components, throttle cable, sprocket, etc.)
• Added basic color liveries (UV mapping for complex liveries has not yet been made pending more bodywork models)
• Tweaked tire slip volume
• Added type hinting and other support for SurfacesFX (for ice tracks, etc.)
• Fixed brake holding not working
• Added visual driver model extended head physics
• Added bumper wiggle physics to nosecone and tweaked other parts' parameters
• Added and configured extended brake system for all karts, including front brakes for DD2 and ROK Shifter
• Extensive tire model config changes
• Retuned chassis flex and damping, fixed oversight with front chassis flex body weight
• Retuned CG position to exactly 43%
• Tuned CG height
• Lowered fixed rear cam (bonnet cam)
