When backend service is down, Node's behavior is unhelpful #543

When the back-end is unavailable (for example: Tomcat has crashed) the front-end's behavior is rather unhelpful: the browser displays an empty page, while Node spews reams of unrevealing stuff on the console.

There's probably quite a few of these. I note that DSpace just sits there running its marching-dots busy indicator forever if Solr is unavailable or if some misconfiguration causes the front-end to request a nonexistent URL.
