recording and playback working

I pushed out a build and sources to Sourceforge.  Moved audio handling into it's own thread.  The "test recording" option records and plays back audio now :)

It worked great for a while on my Blackberry, however at one point the audio completely wedged and I had to pull the battery.  The implementation bugs I'm encountering are very discouraging.  I wonder how things would work on Openmoko.  It's C, and GTK.  Very tempting.

But I've invested a lot in this, so I'm going to keep plugging away.  Next is the network communication.
