Polygon Stripes Feature!
- It's now possible to change the CatMulRom-State of a spline anytime (vice-versa).
- The setup class now initializes 3D graphics related stuff for the new PolygonStripeControl.
- Added road texture and road spline json data.
- Reworked the TransformControl to return WorldUnits if wished.
- Removed old Functions class and added new Utils project to the solution.
