Now pass-through of the Jack input ports is working...  Full
audio recording is now just a simple matter of creating a worker
thread to track the buffer states and flush them to disk at
appropriate intervals.

To my public  detractors(who all happen to own competing
projects, download my software using a proxy so that I can't see
your country, and read these git logs but pretend not to):

About 2 weeks ago, I boasted that I could implement audio tracks
in 2 weeks time...  Not quite 2 weeks later, my success is
imminent, and the product is already quite stable, although I have
more QA and testing work to do...

I also said that I would release PyDAW v2.0 by the end of January...
At the current pace, I could release it sooner, or add even more
features than promised and still deliver on schedule...
