Update to Clojurescript 0.0-2202.

Hi Tom,
 
in Clojurescript 0.0-2202 the `js-dependency-index` fn moved from
`cljs.compiler` to `cljs.js-deps`. This pull requests updates the
dependencies and fixes the import of `js-dependency-index`.

Would you like to merge this and publish a new release? 

Thanks, Roman.
