Title: Travis CI change to get MRI specs green

1. Add Redis to .travis.yml
2. Update configuration to use a valid Rubinius config
3. Make failures of Ruby 2.0.0 fail the spec run (as Ruby 2.0 is a standard config)

There are still some spec failure on the JRuby and Rubinius runs, but currently those failures are allowed.
