Improve traffic behavior

[mole99]

Currently the driving behavior in OpenRW is only rudimentary implemented.

Tasks which should be tackled in the future are:

• [ ] Implement dead ends
• [ ] Implement one-way streets (problem: in our node system we have no possibility to obtain the direction of a street)
• [ ] Add areas where it is illegal to drive (e.g. destroyed bridge at the start of the game)
• [ ] Vehicles sometimes lock each other (maybe add an unstuck activity)
• [ ] Implement different driving styles (e.g. rampant, fleeing...)
• [ ] Implement opcodes (opcode 00ae was partially implemented)
• [ ] Use "smooth steering" instead of directly setting the steering angle
• [ ] Indicate if something is blocking the path (e.g. dotted line)
• [ ] Take account of the debug menu

Traffic director ignores debug menu and vehicles don't use "smooth steering".

Nice feature would be another color for line indicating when something is blocking the path. (Or dotted line)

Just to be clear, while in debug menu the vehicles should not move, right?

Yeah, controllers and all physics should be stopped. It looks like for physics should be created additional issue. Hmm...
