Fixes and Enhancements (#16)
* Add more instructions after successfully creating a new subdomain.

* Update the container name.

* Add a just-in-case step.

* Add an alias and improve comments.

* Fix manage path.

* Add limits but no reservations for PP. Start off somewhat relaxed rather than strict.

* Always restart PP containers.

* Move URL to env file. Do not recommend using HTTPS in the value.

* Format comments.

* Put commands in shells so they cannot exit the full program.

* Updating apps like this did not seem to be working, but also do not want it to work anymore.
