Damage System 2/2 (0.1.5.6)

This update adds the second part of the damage system, which is crash damage, tire wear, drivetrain damage and performance losses for damaged car parts. The damage is set pretty low at the moment and will probably need some further balancing, but I will focus on that once more systems and content is implemented.

For the moment there is no way to repair damaged parts, that will probably be added in the next update or at least in a near future update.

Changelog:

• Completed damage system (now includes damage to car, not only engine)
• Improved AI (fixed bug where they sometimes would just kind of slow down and stack up in corners)
• Fixed bug where the Holler Q4:s rear wheels would turn when giving steering input
