Use the following command to update the copyright year in all files,
starting in the Source/ directory:

find . -type f -print0 | xargs -0
   sed -i 's/Copyright (C) 2012/Copyright (C) 2013/g'

Works like a charm!

Sometimes initialize() returns no error string, but will not find an audio
device, leaving aIOd == null.  This checks for that, and aborts the app with an
informational dialog window if so.

If there was a problem initializing the AudioDeviceManager, we show an
AlertWindow with Retry/Quit options.  Unfortunately, this doesn't fix the bug I
was initially trying to fix, because sometimes initialize() returns OK while
setting the AudioDeviceManager to null.

The AudioComponent now closes the audio device when it's not in use,
saving CPU cycles. Previously, background CPU levels would be between
8 and 10%. Now, when acquisition is not active (and audio device settings
are not being actively edited), background CPU levels drop to 2%. More
optimization will be necessary to get it down to zero, but 2% is still
a big improvement over what we had previously.

The control panel now holds an "AudioEditor" to adjust volume
and open a window to alter device settings. Audio output is definitely
working, but different buffer sizes make it sound really weird. The
same problem is present in the Juce demo app, however, so I don't
think it's a problem inherent in the GUI.
