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!

Added some comments and removed deprecated code.

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

The main UI components now use ScopedPointers for their children,
alleviating the need to call "deleteAllChildren" or "deleteAndZero"
in the destructor.

When many channels are selected for recording a race condition can cause a crash by writing to a file that has not been opened yet.

Cleanups and bugfixes caught by building with -Wall

It's unused, declared obsolete, and is triggering GCC warnings. If
anyone wants it back, it'll be in the Git history.

getInputChannelName() and getOutputChannelName() (pure virtual in the
superclass) aren't returning anything. So far this hasn't triggered
any memory errors because nobody's calling them.

To hack around this, have both of these return
"xxx-UNUSED-OPEN-EPHYS-xxx" (none of the existing subclases override
these methods, so leaving them pure virtual isn't workable). This way,
if we ever start calling these, we'll notice right away that a fix is
needed (instead of segfaulting, etc.).

Also keep them virtual to allow overrides.

That's not gonna work. Since nullParam is just a "nothing found", put
it in static storage and return that.

It looks like declaring them to return bool was a mistake:

1. None of their callers check their return value.

2. They don't return a value, and it doesn't look like there's any
   reason for them to.

If it's for internal use only, then enforce that.

Fixes caught by -Wreturn-type.

Have enable() properly return a value. Have disable() actually disable
the Arduino, and then properly return a value.
