[CM] Builtin audio playback in Grace/SndLib

[Heinrich Taube]

I have built-in audio playback working for .wav and .aiff files in the  
latest version of Grace. I'll be adding other audio formats but i  
havnt had time yet to look at juce's audio format manager to do  
this... The new internal audio playback is assigned to *clm-player* on  
startup so its already hooked into with-sound, and sprout . you can  
also call the play() function directly in scheme, or open the gui  
player component via the Audio menu. (of couse you can set *clm- 
player* to an external player as always )y (the player is a gui  
component so its not in the console cm. ive updated the sndlib  
examples to reflect the new playback facility. the player seems to be  
working great on osx but i have no idea how to get audio ports in juce  
on linux to test it! ive putzed around in Jackctl but i dont see  
anything obvious. (maybe its becuase i only have a linux emulator?)

New binaries of Sndlib/Grace for linux and leopard are up on the page

Other changes:

1. Added menu configuration for a few of SndLib's lisp variables,  
these clm settings are also saved in your preferences file.

2. Added an "Audio Settings..." dialog in the Audio menu , your  
setting saved in your preference file.

2. fixed the parens matching/eval issue in scheme buffers

3. added indentation rule and coloration for with-sound

4. fixed bug that wrote the lunix sound file format on Mac.

---

the biggest outstanding issue is that editing large files with syntax  
highlighting on is still painful due to the fact that buffers are  
based on juce's TextEdit widget.
