Update stop

Hi James. I had some problem with my app deployed on openshift and just did some digging. My Problem was in this stop script. During executions of this part of code: if [[ -f "RUNNING_PID" ]] ... script is looking for RUNNING_PID inside $OPENSHIFT_REPO_DIR, but there is no such file there. RUNNING_PID is being created inside $OPENSHIFT_REPO_DIR/target/universal/stage/. I tested it and it works for me.
