Execute System Tests without JavaScript

Configure the test/system test harness to drive files.

Rack-driven tests are significantly faster to set up and execute, and more closely mimic the end-user experience for a JavaScript-disabled runtime.

In a production application, the System Test suite could be a mixture of Selenium-driven and Rack-driven tests. Striking a good balance between the two is an exercise left up to the teams managing the application.
