Title: Viewport meta tag for testing media queries

To correctly match the width of the window on mobile devices, a viewport meta tag is needed.
You could of course use device-width for this as well, but using the window width is a more generic (and in my opinion) a better approach. Besides, when optimizing content for mobile devices, this tag is usually present.

I tried injecting this tag into the testing-frame, but it didn't have any effects.

Also, the best thing would probably be to add configuration options for these kind of things when starting the server, but that's a bit over my head right now.
