New AI line for Donington Park by Brun found here:

Edited the existing AI line using the AI Spline Editor app and AI hints to significantly improve lap times, improve side by side racing, and reduce crashing.

I welcome anyone to edit and improve this as they see fit.

Thanks to parrilla for his AI line manual.
Thanks to Brun for the track.
Thanks to the creator of the AI Spline Editor app.
