[Tagging] admin_level on nodes: wiki vs practice

See also the use of the admin_centre in boundary relations. This allows
a place to have a different role/importance for each admin area it is
in. An interesting case is Amsterdam, which is the capital of NL but not
the provincial capital of the province it is in (that's Haarlem). The
tagging reflects the facts, and how they are represented on the map is a
matter for the renderer...
