ScreenshotSettings

• Moved the project to the Quilt toolchain.
  • This means it will only work on Quilt, rather than both Fabric and Quilt.
• Fixes a crash caused by taking a screenshot in the menu when using a naming template that relies on world data.
  • (I didn't even know you could take screenshots in the main menu. Why would anyone even want to do that?)
• Replaces the config loading/saving system with Cloth Config's AutoConfig API, but that's a technical detail that shouldn't really impact you as a user.
