long distance path parser: distinguish between station-stop and stop-station terminals
Revert "long distance path parser: distinguish between station-stop and stop-station terminals"

This reverts commit bafd170bbcbd2815b36918bd209f5af33adb1d08.
It is currently untestable but may serve as an example.
Pull TransitStation vertex type out of TransitStop
Merge Jaap's single transfer paths test (7f2afa0)
Allow paths that consist of a single transfer
Test difference between STATION_STOP and STOP_STATION
Allow current vertex type to influence terminalFor
Merge branch 'parent_station_vertices' into propagation
