Openshift deployment scripts

We'll install an alternate version of NodeJS rather than use the
default version so that dev and production remain in sync.

We'll write an env.json file at the repository root so that we can set
application variables based on the values of OpenShift-defined
environment variables.

Use a temporary value of HOME for bower
