[Routing] Routers ignoring speed limits

[Dennis Luxen]

Hi,

the bug was found and fixed in develop branch.

https://github.com/DennisOSRM/Project-OSRM/commit/7c54d4e62fc84b29915dc618fd3dba2962752e92

It will be visible on the routing site in the coming 24 hours. Did the 
bug only affect OSRM or was it visible somewhere else, too?

Best regards,
Dennis
