Title: Bring back Ruby 1.8 in Travis-CI

I am using ruby-thumbor on a project that, unfortunately, is still running on Ruby 1.8. As far as I can tell ruby-thumbor still works correctly under Ruby 1.8 but Ruby 1.8.7 was removed from `.travis.yml` in order to get the tests passing on Travis-CI. I would feel better if future changes are tested against Ruby 1.8 in order to maintain compatibility.

I believe 1.8.7 was removed from travis.yml because ruby-debug19 was failing to install. Luckily there is a feature in Bundler that will us to keep ruby-debug19 around and execute tests with 1.8.7. I needed to add the json_pure gem to the test group in the Gemfile because JSON support is built into 1.9 but not 1.8.7.
