[Tagging] PTv2 public_transport=stop_position for stop positions that vary based on train length

[Ture Pålsson]

Here in Stockholm, trains seem to line up one end of the train with one 
end of the platform. Usually, that's the end where the entrance is, but 
sometimes there are entrances at both ends, so if you arrive just in 
time at an unfamiliar station and find that it's a short train, you may 
be in for a run... (BTDT, with a day hike rucksack...)
