Both solarized dark and light are now included in the subdir
iTerm2. They are copies from the original repo because it doesn't
seem worth to clone a ~10Mb repo just to keep in sync 2 files,
considering that solarized hasn't changed much in the past years.
The rakefile has been updated to trigger the automatic installation
of these two themes only if OS == OSX. The user will still have
to set the themes for his/her current profile manually (but that's
explained at the end of the installation process).
