Missing dependency on clojure.tools.nrepl

[EthanEChristian]

Per a comment on the clara-rules google group,

Exception in thread "main" java.io.FileNotFoundException: Could not locate clojure/tools/nrepl/middleware/interruptible_eval__init.class or clojure/tools/nrepl/middleware/interruptible_eval.clj on classpath. Please check that namespaces with dashes use underscores in the Clojure file name., compiling:(cemerick/austin/repls.clj:1:1)

This is due to an undeclared dependency on clojure/tools.nrpel, this dependency was pulled transitively via leiningen prior to version 2.8.2, however that is no longer the case.

That fix gives me the following issue:

nREPL server started on port 49391 on host 127.0.0.1 - nrepl://127.0.0.1:49391 ERROR: Unhandled REPL handler exception processing message {:id a479569b-999c-42fc-a808-dc4fc9b993c0, :op clone} java.lang.NullPointerException at clojure.core$deref_future.invoke(core.clj:2186)

@jtrunick that works with [nrepl "0.3.1"]
