Add setting for writing dummy CUE sheet comment

If desired, this setting allows disabling writing of the following
comment in dummy CUE sheets:
REM COMMENT "CUETools generated dummy CUE sheet"

- Add setting:
  `WriteDummyCUESheetComment`
  Default:
  `WriteDummyCUESheetComment=1`
  The setting is enabled by default, to preserve previous behavior.
- The setting can be modified by editing `settings.txt` after
  closing CUETools:
  Use bool value 0, to disable writing the dummy CUE sheet comment.
- Resolves: #343
