Beta Leap Of Death 0.5.1

- Fixed bridges hooking on cars/shredding tyres, replaced bridge .dae with one with a rounded collision box.
- Added new texture to the decal roads, a little bit more fitting look, also completed decal roads on the "Quarry Road" around the circumference of the map. All roads are now detectable by AI.
- Fixed water density, lakes will now put out burning cars, and will stop engines.
- Tweaked day/night-cycles a tiny bit.
