Updated to Cascalog 1.10, Clojure 1.4, and Lein 2.0

Thank you for creating Cascalog! I updated this demo to the latest dependency versions. This also changes the hadoop command line invocation (from your blog post) from

    hadoop jar cascalog-demo-standalone.jar cascalog_demo.demo /tmp/follows /tmp/action /tmp/results

to

    hadoop jar cascalog-demo-standalone.jar /tmp/follows /tmp/action /tmp/results
