Title: Mention that Sidekiq 3 requires Ruby 2.0 which will prevent 1.9 installs in the future

This will prevent broken installs for people who didn't read the Readme like they should have, and will have effect once the new Bundler stuff takes hold (http://andre.arko.net/2014/03/28/the-new-rubygems-index-format/)
