Title: Feature/optional apache

I learned bash script while doing this - tested it on two of my heroku apps to make sure it's working. Basically it checks for a Procfile, if found it greps for "web: " inside of the Procfile, and exits with code `0` before getting to the Apache stuff if all that is found.
