Add highway=raceway to roads layer

• highway=raceway, roads and 2, init zoom 13. Around 15,000.

I think this would be in the general (default) kind:minor_road High Road classification.

We do have a kind for racetrack. Should this also get that kind? Or are those completely separate?

Any thoughts for the sort_key? Or will the default work?

Different kind. Racetrack is more for people running. Raceway is for cars driving fast.

We need docs, starting that work with:

• Add kind definitions for pois / landuse #802
• Add kind definitions for roads #803

Any thoughts for the sort_key? Or will the default work?

It should probably get it's own. We're putting it in minor_road, but sometimes shouldn't be symbolized like that (and would z-fight tilted). Propose something? Might impact a few tests :\ So bundle up with #605?

I made the sort_key one higher than links, and bumped those down one in 038d56d.
