Inofficial minimal setup for BackstopJS

See: BackstopJS automates visual regression testing of your responsive web UI by comparing DOM screenshots over time.

BackstopJS is an awesome tool to do visual regression tests. In the basic setup, there are a couple of configuration options that are required that I don't really care about. So this setup has the goal to need as little configuration as needed.

To use this setup:

• merge you package.json with the one in this repo.
• add tests/backstop to you repo.
• install npm packages
• adjust config.js and scenarios.js
• run backstop eg. npm run backstop:test and npm run backstop:approve - see package.json for scripts

Thanks to the BackstopJS contributors for providing such a valuable tool!
