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!

Generic changes:

- Genuinely unused variables (-Wunused-variable): delete
  them. Sometimes add a comment if the variable is for an extension of
  the code that isn't done yet.

- Variables that became unused due to commented-out
  code (-Wunused-variable): comment out their definitions. Dirty, but
  that's because commenting out code instead of deleting it is
  dirty.

  Many of these are due to commented-out printlines that should have
  been log messages that only get emitted at high verbosity level.

Specific changes:

- SpikeObject.cpp (-Wunused-value): move initialization of loop
  variable into first for loop clause to silence the warning.

Added typeface initialization to CustomLookAndFeel, and implemented
getTypefaceForFont().

Fonts can now be created using a more centralized method, by calling the
Font(String("Typeface Name"), fontHeight, Font::style) constructor.  Names for
the typefaces ("Default Light", "Paragraph") should be regarded as tentative.

There's also simpler code to do the same thing that should be uncommented after
the 2.0 update (it uses HashMap, which is not currently in our library code,
even though it's in the 1.53 docs.)

Tabs now work reasonably well when right-justified.

Border is now a square (except for upper-right corner).
