Location of stations

[Phyks]

When in station details view and clicking the top right corner button, station should be in the middle of the map, with marker opened.

Back button should return to previous view (map) as does the top right corner button at the moment, no? @eliemichel

Or better, click on the pin button should center the map on our position + the station position, and draw a roadmap between them.
