Freedom Factory AI Races 2.5

- Updated AI path and settings to make them work with Beamng's updated AI
Note: The AI are now slower. I made them as fast as I can with the Mission Editor. We only have one adjustment that controls two things. The speed and the chance of them making a mistake. So the faster they go the more they mess up. (maybe the Devs can split that into two adjustments at some point}

-Added ability to start the race from the "Scenarios" tab.
Note: loading the race this way will make the screen go black for 30-60 seconds while things load. It may look frozen but it is not. (Hope the Devs can add a loading bar or something)
