List of game changes

Hello,

The bug of the pit stops and tires should now be fixed.
Don't forget to add pit stops for tomorrow' race.

There's a new button in the strat page. You can now apply your car's settings to all of your other cars automatically.

I did a few changes to the race page:
- you can now view the gap between a driver and the driver preceding
- there is a new list containing all the best lap times

I added information about the race group number of your driver on the training/qualifying pages.

You can now apply your pit stops strategy to all of your drivers in one click.
