escape # in first keysound entry, fixed ADPCM reader and make PMS load more correctly.

- [NoteField] fix build warnings, and change the maximum number of displayed notes
  after the receptor to 64.
- [Player] fix build warnings.
- [NotesLoaderSSC, NotesWriterSSC] The MSD file reader seems to treat # that comes
  directly after : as new tag, and as many PMS and BMS files has keysounds which filename
  starts with #, so it looks like this: #KEYSOUNDS:#bgm.wav,01.wav,02.wav,..
  The MSD parser will see it as 2 different tags. So I added a backslash in front of the
  # sign if it's at the start when saving and remove it when loading.
- [RageSoundReader_WAV] ADPCM now works very well and doesn't return error when
  end of file is reached anymore.
- [Steps] Use BMS loader when loading the note data.
