First version of my mpeg audio datatype. Uses mpega.library to read audio
files (e.g. mp3) and plays them using AHI. It does not yet support to save
the raw sample data.

68k and OS 4.0 version included.

History:

20.5 (descriptor only)

- improved descriptor file again. Now ignores RIFF WAVE files and
  files with only one frame (e.g. small PNG pictures)


20.4

- improved descriptor file. Uses mpega.library again but tries to decode
  the first ten frames. Should now recognise every file the class is able
  to play.

- MultiView now shows the correct name in the title (DTA_ObjName attribute)


20.3

- slightly improved descriptor file. Not perfect yet but should fix the
  problems with pictures being recognised as mpegs.


20.2

- bug fixed: failed to initialise if sound.datatype was not already loaded


20.1:

- initial release
