[Tagging] service=rural (Was Rural Alley?)

I think an additional tag is not necessary.  I think is is sufficient
to tag them with highway=service.  Remember, service=* is simply
clarifying the kind of service road.

They are definitely not tracks.  I remember the discussion about
clarifying track grade 1 and I thought it was stretching a point.

Routers should have a concept of a road hierarchy, and should "prefer"
higher-classed roads (unless the user specifies otherwise).  The
simplest router could then make a good route by looking only at
highway=*.  Maxspeed, lanes, and other information can refine a route,
and help make a choice between a speed-limited trunk road and a
longer, but unrestricted primary road, for example.

To me, the hierarchy is obvious: motorway, trunk, primary, secondary,
tertiary, unclassified, service, residential, track.  No matter what
grade a track is, it should never be chosen in preference to a service
road, or unclassified.
