Update to ClojureScript 0.0-2371 (stable), patching for compatibility.

Just updating the ClojureScript dependency to the latest stable 0.0-2371 (as of now), and fixing couple of lines which were broken by a ClojureScript stable [here](https://github.com/clojure/clojurescript/commit/4fba4f13e1603cc12215f0d66fd62f5fd043f528).

I ran the `lein cljsbuild test` on changes, all passing, 0 failures, 0 errors that's.

P.S. My first contribution on a GitHub (about time). Палками не бейте, пожалуйста!
