Update ruby version

[shawnjohnson]

I'm not really sure if this would cause any negative impacts, but I noticed github pages is up to Ruby 2.1.1 - https://pages.github.com/versions/. Personally I get a warning about the currently specified version (1.9.3-p392) on Mac OS X, and it doesn't happily install via rvm.
