Release 4: Audio, Patterns, Updated things for Quest 2, Menu Freeze

Hello!

Release 4! Not much added to this one as last time but this update will make everything going forwards a LOT easier. It adds:

• Audio! Only one audio track so far, made by myself, so you have something to listen to while you enjoy the spirals and all.
• Patterns on shapes! 5 so far, so you can create some really extra-lookin' stuff. Allows for more variation.
• Comfort! You can now freeze the main menu so it stays in place while you do everything else. Some folks were complaining of motion issues, so this one is for you. A few other little things too to make it just, work better.

The program has been updated with the latest Quest 2 stuff, so it SHOULD work for Quest 1 and 2 seamlessly, but I have no 100% on that. Let me know, eh?

As usual, let me know of any issues!

Thanks! <3
