I added it to the sprite image. I intended to do this, but neglected to
followup

This is the order of steps to add to the sprite image.
1. Place the image in icing/ (we already had tour-icon)
2. Create a class like this:
   background-image: url(/@@/tour-icon); /* sprite-ref: icon-sprites */
   background-repeat: no-repeat;
3. make sprite_image
4. make sprite_css
5. make css_combine
6. make run.
7. verify you see the icon on the element
8. inspect the CSS applied to the element
   and verify that background-position was added.
9. commit the changes to the generated files.
