Enhancement deployments

- Expanded firewall rules for the various components in a Deuce deployment
- Documentation on using the firewall rules, with examples for UFW. (IPtables examples are too varied to provide)
- Documentation on deploying Deuce using either Apache2+mod_wsgi or Nginx+gunicorn.
- This provides in-repository documentation on some of what was done to setup the test environment, but only covers the configuration information.
- Added scripts for start/stop/restart of gunicorn_pecan

Note: I did actually deploy using Apache2+mod_wsgi temporarily. I replaced with Nginx+gunicorn while trying to figure something out that turned out to be a problem in my testing script, not the deployment itself. So the Apache2 configuration should be very close to correct.
