Took the liberty to drop build the batch list in the ```setup``` as we're using it in nearly every test :wink:, hope it's okay. I also dropped all the ```\t``` in exhange for soft-tabs. Thought it would be ok as I'm just following the coding style in the [Ruby Styleguide](https://github.com/styleguide/ruby) which is referred to in the [Jekyll Contributing page](http://jekyllrb.com/docs/contributing/)
