[Tagging] Trailhead tagging

Just as we do not map a wikipedia link to shop=car to explain the
concept for shops selling cars, we should perhaps not map wikipedia
links to explain TOPs.
We do not link nodes and routes of walking networks to wikipedia pages
(or other sites) explaining how you have to use them.
We do not link highway=motorway to a wiki page on osm.org to explain
the meaning of that concept.

Exactly the same information, on exactly the same amount of nodes, just bypassing the existing referencing mechanisms, making it useless. The prefix keys are useful if multiple wikipedia references are applicable (according to the mapper).
