v1.28: VR list scrolling + easier return to the same song

• You can now use your VR touchpad or thumbstick to scroll up and down the music list. Use both thumbsticks for more velocity. You have to be pointed at the list for it to work.
• When you complete a song and return to the song selection screen, it will automatically select the same song. This makes it easier to redo the song and see saved high scores.
