snd and clm news

[To: cmdist]

New Snd has a variety of colormaps for pretty sonograms,
a color and orientation browser, a much improved save-as
dialog, a new files browser, and an improved region browser.

At Tobias Kunze's suggestion, I added the generator rec-any
to clm for real-time microphone input.  Also the help
facility is gradually moving beyond the 1960's. In Linux
I removed the :voxware switch because that code is apparently
a standard part of the kernel (similarly in Snd).
