Old example screenshot with filenames

[esseb]

The example screenshot used in README.md has this as the first warning: autoprefixer: menu.css:4:4: Outdated direction syntax in gradient

From what I can tell from https://github.com/postcss/postcss-browser-reporter/blob/master/index.js#L71 this warning would actually look like this in the current version: 4:4: Outdated direction syntax in gradient [autoprefixer]

If I'm reading the code right and filenames really have been dropped, the screenshot should be replaced with something more up to date. I was trying to figure out if anything was wrong with my postcss setup because I just couldn't get filenames in my postcss browser reporter toolbar.

Filenames would be useful though, maybe an optional config?
