Unsupported Luuks Tyre Thermals and Wear Mod 1.3

Update v0.3:
- Big overhaul to the temperature system, now using a 3 ring system and incorporating camber and side-to-side load to approximate the contact patch (still pretty rough);
- Tread coefficient on tyres used now, to support standard and sport tyres as well;
- More tweaking done to all the values and the UI to fix various problems;
