Feature Request: Create Gemfile and Docker File

[gardnerapp]

Good morning ! I was trying to use this tool for the RedTeamCapstoneChallenge and found that installing the right Ruby and Gem dependencies to be quiet a hassle. I've started writing a Gemfile to track and maintain a consistency of the Ruby version used by the script and Gem dependencies. Could you provide me with the version of Ruby and Gems used in your original development environment? Try: ruby -v or gem -v httparty.

Additionally I've started creating a Dockerfile to package the app and make it easier to run without having to install Ruby and a bunch of other gems.
