Title: Add support for command prefix.

We use foreman to generate upstart scripts for use on production with Docker. To achieve this we specify a prefix like:
```
docker run -v /data/tmp:/tmp -e RAILS_ENV=$RAILS_ENV -e PORT=$PORT -e CUSTOM_LOGFILE=STDOUT
```

That way we can still use foreman for local dev.
