More bug fixes

- BPM and go go time change even when there are no notes after the change, seen in Ego Ego Atakushi and UFO Swingin'
- Maker URL can be added to a local tja
  - Example: `MAKER: Creator name <https://example.com/path>`
- Long list of settings scrolls more naturally with arrow keys
- When media engagement is low, gamepad users will not be able to proceed on the title screen until a mouse click or a key press unpauses the audio context
- Fix "Bad" note gauge judgement on easy difficulty
- In debug, use hash to tell apart songs
