To run this in the future, install astyle (sudo apt-get install astyle),
then enter the following from the top-level project directory:

astyle --options=astyle.options --recursive "./Source/*.cpp" "./Source/*.h"

This will convert tabs to 4 spaces and ensure that brackets are on
their own lines.

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!

Channel selector buttons now can be used to toggle audio monitoring
for individual channel. One minor bug: the array of channels to monitor
is not updated when the graph is rebuilt. If new processors are added,
the mapping might be wrong.

Since every processor now gets asked to enable() prior to the start of
acquisition, it's much simpler to move the steps involved in preparing
for acquisition into these methods. This the processor from beginning
acquisition when prepareToPlay() is called upon initialization.
