Automate config tests

[jefflester]

Tests for the config command should be automated and incorporated into the runner.py test runner file.

The challenge with this is that the command opens a text editor. I am trying to figure out a solid way to capture the correct exit code and also hop out of the text editor automatically. So far, my efforts aren't going anywhere.

For the time being, human QA will be run on the config command prior to any releases. This should be considered a high-priority testing item to ensure all commands are getting equal testing coverage in the testing library.

This isn't worth the effort to automate at this time, as the config command is extremely simple.
