* Added custom audio processor editor for CAR plugin - CAREditor;
* Added buttons to switch between "Reference" and "Affected" channels;
* CAR processor some minor changes;
* Some minor changes in GenericEditor class which provide more
  possibilities for plugins (e.g. plugins can implement their own
  resized() methods, etc.);
* Added UIUtilities header file in which we can include any
  UI components/utilities which will be useful for easier plugin
  creation.

Allows parameters to be set from saved XML and changes the
parameterEditor buttons (currently for discrete parameters only) to
reflect which parameters are currently used by selected and
non-selected channels. This fixes a problem where the buttons would
always show what the last press was rather than the current values for
the active channels (e.g. If you changed the parameters on Channel 2,
and then switched to select only Channel 1, the GUI would incorrectly
indicate that the settings for Channel 2 were active). Additionally,
allows the user to see what parameter values are used for channels not
currently selected.

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.

With new jucer, windows.h is not only unnecesary, but can cause conflicts with some definitions.
Also, OpenGL.h includes disabled, as it's no longer needed and it, by itself, needs windows.h

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!

Through the SpikeDetector Editor, it's now possible to change the channel
mapping for each electrode and adjust thresholds. It's not yet possible
to inactivate particular electrodes or change parameters over multiple
electrodes at once; these will both be necessary functions in the future.

Channel selection now takes place within a slick new interface. It's not
yet tied to actually changing parameters, but things should be much simpler
code-wise, as well as visually.
