Integrate with Travis-CI

Now we have removed the dependency on an external site for our example features, we can integrate Quke with a CI service.

This change sets up the project to work with Travis CI so future changes will automatically be tested.

 A template repo for building [Cucumber](https://cucumber.io/) feature tests that can be run against a web site. Unlike normal setups the feature tests do not need to be included with the source code for the site to be tested. Instead this template project includes the ability to run them standalone.
