Title: Deprecate old versions of Ruby

We've got a considerable burden maintaining compatibility with Ruby 1.8 and 1.9.2. These versions are no longer maintained by the Ruby team and are not supported with modern versions of Rails and other gems.

We can safely remove support for these with the next major version release.
