Simplify StreamCapturer for subprocess testing...

Simplify StreamCapturer for subprocess testing Rather than using a transient pipe for each subprocess started, the StreamCapturer now makes a single pipe, and subprocesses redirect their output to it. So long as this works on Windows (I've done brief testing, and os.pipe() seems to be functional), this will hopefully make this much more robust. The recent failures in ShiningPanda on IPython.parallel have been caused by StreamCapturer.
