[WIP] AC Scenario mode

If you want an arcade experience of Tokyo Xtreme Racer Zero, this is the closest you'll ever get. This mode works as you'd expect, pick an entry point for the Wangan network of highways, a car, and of you go!

The structure of this mode is pretty simple, win 8 stages and you'll successfully complete it. If you do that under some circumstances, you'll get a reward. Here are the requirements necessary to fullfill in order to get them:

• Use a stock car or Tatsuya's Porsche RUF 911 (964) RCT: unlocks the Nissan Fairlady Z (S30) (type A) from Akio Asakura
• Use Akio's Nissan Fairlady Z (S30) (type A): unlocks the Porsche RUF 911 (964) RCT (type A) from Tatsuya Shima
