- wrote a lot on the deployment chapter

- big changes, not finished yet, but need to move my work to a
  different server because BASH on Mac is a joke, so the documentation
  build will not fly.
- 'go to' is two words.
- re-wrote great parts of the deployment chapter using ece-deploy
  instead of 'ece deploy'

- explained the ece-deploy roll back mechanism

- explained rationale behind the ece-deploy IDs and deployment log
- create-handbook.sh now creates a variable, trail_virtual_host_list,
  from the trail_publication_domain_mapping_list. This way, the users
  only need to list the domain names once.

  The trail_virtual_host_list can be used in the documentation
  whereever you need to list all the domains that the servers are
  delivering.
