Add full screen diff to needle preview
Since https://github.com/os-autoinst/openQA/issues/707 we lack a good way to see the full screenshot of the needle. We still want this back to debug things - right now, (operators) can go into the needle editor and select the right selection of combo boxes to see it. But it should be easier than that.
