Added javelin clojurescript implementation

I have added a todo project that was implemented using javelin using a pure clojurescript approach.

This differs from hlisp-javelin implementation as it does not embed any code within the HTML code itself. It is more suitable in situations where the design template should have as little code as possible.

Squashed here for you to verify. Demo can be found here: http://priornix.github.com/todoFRP/todo/javelin/public/index.html
