Nova Frontier Circuit and Manual driving tweaks: update v0.1.11 — Pioneer Racing Steam update #566541

version 0.1.11 changelog: added several buildings in the nova frontier circuit made Nova Frontier circuit a finished map; now working on two other ones corrected the reverse function: now reverse as brake is deactivated, reverse switches automatically when automatic gears is selected and the car is almost at stop, but it doesn't when the driving mode is manual. corrected car behavior when oversteering: some cars now have more adherence, steers better, and don't do barrels for a small steering angle.
