Fractal Fly update notes - v1.2022.2.19

- Display a message if VR wasn't able to activate, explaining the issue and how to fix it (have to set OpenXR defaults to SteamVR).
- In Screen (non VR) mode, add X and Y inversion setting for pad and mouse movement.
- In VR positions controllers away by default, so they are not annoying player sight when controllers are still not activated.
- Prevent the gamepad cursor to display when in VR mode.
