Fixes #42 (incidentally)

[arschles]

is there a simple way to indicate what to look for in the above two sets of logs?

[jchauncey]

Heres what it looks like -

╰─± deis logs
Error: There are currently no log messages. Please check the following things:
1) Logger and fluentd pods are running.
2) The application is writing logs to the logger component by checking that an entry in the ring buffer was created: kubectl logs <logger pod> --namespace=deis
3) Making sure that the container logs were mounted properly into the fluentd pod: kubectl exec <fluentd pod> --namespace=deis ls /var/log/containers
