- Traditionally all of Ghost's public-facing text was written in British English
- We're changing that to US English because that's more common
- US English should also be used in code e.g. properties are called color not colour
- most of these changes are in comments, but I've changed them so that we have US English in front of us always
- fixed a few other typos I noticed whilst there
- starting and stopping Ghost is part of our rather unloved acceptance test framework
- moving them into their own file to make the different pieces clearer and also to start to make improvements
- first improvement had to happen as an aside - exposing the existingData property via a function and making the API clearer
- this was a weird thing set on module.exports, very hidden and hard to follow
- Note: stopGhost is only used once in the regression/modles/model_posts_spec.js file to make the test run fast enough...
- These tests are effectively "DB integration" tests e.g. non-unit tests because they do use the DB, they need their own framework
