[Etoys] Ogg Vorbis and Speex CODEC for Squeak eToys

[Takashi Yamamiya]

Hello,

I have uploaded some change sets to the update stream (#1230, #1231)
for Ogg Vorbis and Speex sound codec support. It allows you to
compress sound data efficiently, and it would be easy to make tutorial
project with voice guidance.

- Recoding a voice with codec using Sound Recorder in parts bin.
- Making a tile from the recoeded voice, and saving as a .pr file.
- Playback .ogg / .spx music from File List.

I will apply the Event Theatre soon.

However, you need a plugin file to test this feature. Please download
and try it.

for OLPC machine and linux.

for Windows

for Mac OS X
The mac plugin requires universal binary

time to build something on Macintosh, it is possible that something is
completely bad. At least it worked on a MacBook though, please tell me
if it doesn't work on your mac. And give me your advice!
