Update, Racetrack Generator

FPV Freerider Classic has been updated with a racetrack generator that uses procedural generation to create an almost infinite variation of gate arrangements. Some of the latest changes to the simulator include: - Racetrack Generator (Generate millions of tracks automatically) - Completely new Self-Leveling mode (Angle mode - set maximum tilt angle) - Side-by-Side VR view (as previously available in the Android version) - Rates showing as degrees per second on the custom settings screen - Adjusted the Preset rate values - Yaw now also has expo - Four expo curves in total (Expo1, 2, 3 and Linear) - Opened up the Playground map a bit, also made it more efficient - Square gimbals on the touchscreen controls (meaning full stick throw in all directions) - Changes to the flight sound - Hotkeys for flightmode: U,I,O (Self-Leveling/Acro/3D) - Groundeffect simulation
