This fixes transfer trains getting lost when requested from a related station

Notable offender: "Berlin Südkreuz" lacked S 41 / S42 (ring line
from Südkreuz (S) to Südkreuz (S) with transfer to/from the next/previous
incarnation), as it referenced "Berlin Südkreuz (S)". "Berlin Südkreuz (S)"
itself worked fine.

Happy New Year!

stations.json: Update Lindau

Add Lindau-Reutin and rename Lindau Hbf to Lindau-Insel

most belong to SEV though

Those are only needed for db-iris and thus not included in Build.PL
