Title: full width instance background

This changes the instance subheader background introduced in #793 to stretch across the whole available space instead of filling 120% if `.page_wrapper`.

Maybe we should ask someone from the office before merging if this is really what they want.
A possible issue is that we have absolutely no control over the ratio of the image. But with the upcoming responsive design we don't have that control anyway.
