Imola Chicane Layout 1.0

Added the chicane which is used as the "moto" layout to the track, probably the closest we're gonna get to the old layout that was used before the big rennovation. This also means the grid is moved up to the old starting positions. Had to make a new AI line but I'm a terrible driver so if anyone wants to make a new one that would be great . One issue is that the run off markers on the original straight fall through the floor if they're hit, it's my first time messing with objects so any help with that would be much appreciated.
