Fix `lein doc` (with codox "0.6.1") and a HTTP 404 for our own javascript problems.

For `codox "0.6.1"` to work, explicitly stating that routes.clj is using `{{name}}.handlers.home` is required. I cannot get a more recent version of codox to work though - not yet sure why, still looking.

Our own javascript is not located under vendor, looking in a higher directory.
