Update Documentation for supported Drupal versions

Problem/Motivation

The documentation for this project only covers deprecated versions of Drupal. The screenshots are referenced via links (which are broken) rather than being uploaded against the documentation node directly. Due to these issues, the documentation page has been marked as deprecated.

https://www.drupal.org/node/716142

Proposed resolution

1. Update the documentation and screenshots to a supported Drupal version
2. Upload new screenshots into Drupal.org
3. Update links to screenshots to point to Drupal.org hosted images or embed the images directly into the documentation page

Remaining tasks

This issue was created during the DrupalCon New Orleans 2016 mentored sprint.
