Initial namespace not setup properly

[andykitchen]

For some reason, when using exec-env through cljs.repl/repl
the default namespace isn't initially set-up correctly causing syntax
errors in the generated code.

Austin is not compatible with ClojureScript 2156 and 2173; just about any other version will work. See #55.
