MidnightLib 1.5.0 - 1.20.2, slight redesign & cleanup

- Port to 1.20.2
- "Reset" button now uses a custom icon (closes #25)
- Config instances can now specify custom config change behavior (implement "writeChanges" method in your class; closes #33)
- Remove TexturedOverlayButtonWidget (replaced by vanilla's TextIconButtonWidget)
- Removed radialRainbow (used very rarely)
- Updated AutoCommand to support editing list and float config values via commands on serverside installs
- Reworded description
- Forge & Quilt temporarily disabled until they release, as always
