fix WordCountJob package; tests; hadoop version
When copying from upstream scalding, forgot to change the path/namespace of the WordCountJob. Production IA cluster is actually running Hadoop 2.5, not 2.6 (I keep forgetting). Pull in more dependencies so test runs (copied from scalding repo, only changed the namespace of the job)
