This is a relatively small but worthwhile update, I redid all the Formula Pretend cars from scratch, you will surely recognize the liveries, I still have a couple more to do but I am trying to improve the base template before finishing those.

This new version also updates Bristol, it is now a proper oval, using the new curves that were first introduced with Catalunya.

Update notes for build 20200727
- Redid Bristol layout, now its a proper oval
- Updated AI for new Bristol layout
