NEVERHOOD: Add initCubeSymbolsPuzzle

- Add microtiles to the screen update to eliminate overdraw
  (microtiles code taken from the Toltecs engine)
- Fix sprite dimensions in AsScene1402PuzzleBox which caused a crash
- Fix screen shaking in Scene1402
  (the puzzle box and bridge parts now shake along :)
- Use addSoundItem/addMusicItem in the SoundMan instead of
  directly using push_back on the resp. arrays
- Remove old code and comments
