Add non-interactive script options and fix nginx container name (#12)

Browse Source 
* Add non-interactive script options and fix nginx container name

Nginx container name was hardcoded even though a different name is defined
in docker-composer.yml. Script will now detect proper name from docker-compose
file.

* Fix invalid boolean variable comparisons

* Refactor user confirmation prompt logic
