[Audacity-nyquist] Nyquist Effect Workbench ... final

[Leland <le...@au...>]

I believe I've fixed everything mentioned and have added:

1)  an About dialog
2)  Toolbar, menu items, and accelerators for moving to toplevel s-expr, 
parent s-expr, previous s-expr, next s-expr, and jump to matching paren
3)  Paren highlighting works with the mouse now as well
4)  Window size and position are now saved
5)  The ability to run arbitrary XLisp/Nyquist code...doesn't have to be 
an Audacity effect
6)  Running programs can now be interrupted with the Stop toolbar 
button, menu item, or accelerator

If no one finds anything wrong, I'm considering this complete and 
(probably) won't add anything else to it other that use it to experiment 
with external module APIs.

It can be had from:
