upgrade to wiki-0.14.0 and move configure-wiki to separate step

We should only need to run the configure-wiki script once instead of
every time we start the container.  Also, I don't think that script
was correctly handling PID 1 role (e.g. don't think we forwarded
signals to node nor reaped zombies)
