SongSelect: Add Settings

- Resolution can be adjusted, as well as touch drum animation on mobile
- A translation text file "songtitle.txt" can be imported
  - Titles and translated titles are each on their own line, if a line begins with a language code, it will translate the song title that is above
  - An example file can be found here: https://gist.github.com/LoveEevee/65fe66f0b54c0536f96fd2f4862984d4
- The page will fail to load if version on the page does not match /api/config
- Disabled Tab key while playing, before hitting it would focus the version link
- Fix forcing branches in debug not working
- Fixed not being able to click on songs that do not have oni but have ura
- Fix unexpected category being used as a fallback
- Fix verticalText and layeredText not accepting anything except strings
