New track: Jarama (missing tex)

[thelusiv]

This track is a whole lot of fun. alexr committed it a few days ago, and it is so good, I think it might be added to the minimal data set for next release. All the friction and bumpiness settings are correct making the sand traps and grass realistic, our second track to use this in the new track system (note...somebody fix this... ).

However there is one little tiny problem. The texture is missing from the track where the car starting spaces are. In the track shot this area is visible and looks like it has oil and skid marks from cars, but in the game, it looks like a lot of big white rectangles before the starting line.
