The change to the template file is just to include my custom css on line 42, you can add the line yourself if you wish together with the CSS and image. It overrides the default CSS, so you can just remove the CSS-file if you don't like it. Instructions on Github. You can in theory apply this to all the other template files as well, but I didn't really care for those. Do as you wish.
