[openrailwaymap] Tag railway=station on ways and Wiki

Hello Mauro,

I prefer the passengers view of a station or halt. If we will meet "at 
the station" where are you expecting to find me? This is the position, I 
usualy use for placing the railway=station node, definitly not on a 
track. The track carries nodes like public_transport=stop_position. 
Putting 'station' on a building or even a larger area leaves it to the 
renderer or any other data consumer to guess the center of the station 
from passenges view.
