- Clean up methods in GenericProcessor

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.

For some reason, "getCustomTypefaceForFont" wasn't being called on OS X.
It probably has something to do with platform-specific code for loading
fonts. Now, in cases where custom fonts are needed, loading requires
4 lines instead of 1. Kind of a pain, so hopefully this is a temporary
solution until we can figure out what's different about Macs.

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!

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

Rearrange member initialization in constructors to silence GCC
-Wreorder warnings (-Wreorder is enabled by -Wall).

VS throws errors in several locations about ambigious type casting.
Fixed by removing the ambiguities and casting things to double.
