F-Sim|Space Shuttle 2

This is a minor update with bugfixes and some new features: New features: - Background audio (e.g. playlists from Apple Music) can now be played back instead of F-Sim's in-game music. This is optional and must be enabled in the F-Sim's Sound And Vibrations settings. - RCS controls (in orbit mode) now always use virtual sticks instead of tilt controls - New autopilot wheel-brake option The following bugs have been fixed: - Wheel bounce detection is now less aggressive - Fixed a bug with terrain collider updates (this bug sometimes caused the Orbiter to jump during rollout when the framerate was low) - Fixed a couple of bugs concerning wheel brake control during rollout.
