#244 SVG images are delivered with the wrong mime-type

I just uploaded a new repository here: https://notabug.org/nipos/cloud-firewall. The README contains a SVG image which should be shown where you can read the alt text "Badge for Humane Technology listing". I checked the source code and it looks like the HTML is loaded correctly. The image isn't shown anyway because the server delivers the SVG file with an text mime-type and not with image/svg+xml as it is expected by the browser. Most likely this is caused by a outdated Nginx configuration which doesn't know the SVG format and just defaults to a text/plain mime-type. It would be nice if you could repair the mime-type so that my image is shown.
