fix typo in message
Merge pull request #60 from lagartoflojo/master

Fix a small typo in the comment.
Fixed :each VS "each" conflict in method list inclusion.
updated koans with latest src
removed deprecated require of rake/rdoctask
Silence complaint about Rake::DSL
Back ported a lot of changes made to the Koans directory.

Evidently, a lot of changes / pull requests were made to the koans
directory and not to the src directory.  Perhaps we should remove the
koans directory entirely from the repo.
Handle 1.8 VS 1.9 differences in fetch exception.
Add a dummy KeyError to 1.8 so that src koans will run.
Removed support for Ruby 1.8.6.
Added __ to assert with no __ blanks.
Updated koans directory from source.
Restrict assert checks to .rb files.
Remove koans directory from source control.

Patches were submitted against the koans directory rather than the
src directory. This lead to potential problems when we regenerate the
koans directory from scratch, leading to the very real possibility
that changes could be lost.

Please make all changes to the src directory and use "rake gen" (or
"rake regen") to generate the koans directory as needed.
Added koans directory to the .git ignore list.
removed duplicate word "The" in comment.
Compare strings instead of symbols for constants, similar to method names.
Merge pull request #64 from RichLewis007/master

Fix typo in comments in about_sandwich_code.rb
Fixed color support in OS X
updating README with directions for generating the koans
