added https://github.com/gatapia/nclosure for nodejs

Reference: http://dev.clojure.org/jira/browse/CLJS-101

You need to install https://github.com/gatapia/nclosure
Test project, https://github.com/harsha-mudi/nclosure-cljs-sample

Caveat: You probably don't want absolute paths in the deps.js file
