v0.10.0: New Core GTFS-RT

The new core can now be updated with GTFS-RT real-time updates (currently, only delay updates are supported). The real-time routing of the nigiri module considers those real-time updates. The map and train run display are not showing real-time updates yet, because those depend on the old core.
