Fix music selection to match TU19 behavior

Menu music (menu1-4) now plays only on the title screen, creative
music (creative1-6) only plays in creative mode, and survival mode
correctly plays only calm/hal/nuance/piano tracks. Reordered the
eMUSICFILES enum so piano tracks are contiguous with the survival
range, added game-mode-aware track selection via getOverworldMusicID,
and re-enabled the playStreaming call in setLevel to stop menu music
when entering gameplay. Added debug logging for track selection.
