Indianapolis Speedway (CART 1998) 2.0

Hi all.

Here is Indianapolis speedway for GSC, Cart version.
Credits to RacerAlex I could not contact (no mail, no link...).
He did a nice pdf presentation of the track.

Well, very old track but I did my best to update it. Some things would deserve a deeper update but unfortunately it is not possible.

It is already ok in the trackbase.ini for the chassis.

Thanks to denis for loading screen and minimap.
