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!

MainWindow now points to the ProcessorGraph and AudioComponent
with ScopedPointers. deleteAndZero must no longer be called
in the destructor.
