Version 1.16.16

- Fix: hang in train simulator when combining stop selection signals, platforms in series with the first platform being occupied, switches in the middle of platforms and trains too long for the stop area and being forced to stop over the switch
- Fix: crash while visualizing pax path routes on the map and at the same time deleting tracks or stations involved in said routes
- Fix: attempting work around for crash in the train info window accounting tab, which cannot be reproduced reliably
- Fix: station editor stop signal pick mode should not display signal buttons if signals are not visible
- Fix: some trains stopped at signals had incorrect signal stop time stats
