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

Fix code

- Fixes code

SoundBuffer: Set song volume

- Requires a new column in the database after preview: `volume` REAL
- The value is a volume multiplier, if the value is set to null or 1 there will be no change
- The volume can be set in debugger
- Imported TJA files are now read from disk every time the song is played, freeing some memory and making it easier to create charts
- Correctly parse TJA files with alphabet notes, added "A" and "B" notes, which appear as DON (Big) and KA (Big) respectively

View: Fix donbg scrolling

- All metadata fields in imported TJA files are now optional
- Added new metadata fields: `TITLEEN` and `SUBTITLEEN` (`EN` can be any language id from strings.js)

Game: Fix notelocking

- Will not skip the note if `ka` was pressed right before `don` note or `don` was pressed right before `ka` note
- Will still skip the note if `don` and `ka` is pressed at the same time (within 25ms)
- Fixed `TAIKOWEBSKIN:` in imported songs crashing the game with some values

ParseTja: Add branches

- Needs the following changes to the database: change `easy`, `normal`, `hard`, and `oni` to `TEXT` type
- When adding songs to the database and if, for example, a song's 7-star difficulty has a branch, instead of `7` input `7 B`, this is to display song's branch support on the song selection
- Branch can be forced in debug

- Fixed gameend being sent twice in p2
- Add `ready`, `loader-error`, and `song-select-random` events
- Fixed `session-start` not firing when invited, added event detail
- Fixed `language-change` being fired at startup
- Fixed `version-link` and `about-link` firing twice
- "#song=" will fire `song-select-difficulty`
- Removed `key-events` and `scoresheet-player2`, merged with `scoresheet` and made it more detailed
