Link to wikipedia articles on wikipedia=* tags

Browse source 
The semantics are as documented on
http://wiki.openstreetmap.org/wiki/Key:wikipedia, i.e.:

    # English Wikipedia article Foobar
    wikipedia=Foobar
    # German Wikipedia article Foobar
    wikipedia:de=Foobar
    wikipedia=de:Foobar

If someone gives a http:// link we just pass it through.
