Minor touchups to challenges menu drawer

See merge request KartKrew/Kart!973

- `tunes -show` now shows music_name rather than mapmusname
- `tunes -showdefault` does the previous mapmusname behaviour

- Drawn over the top of basically everything when enabled.
- Update song credit on
    - Menu music update (can sometimes clear it)
    - Intermission begin
    - Vote begin
    - Return to title (by clearing it)

- This only happens at the very end of PR_LoadProfiles, so it marks the clear point data is good.
- Resolves #451
