Restore GTFS realtime, show type of vehicle in the map
Summary:
Fix URLs (needed https asd)
Prepare for showing alerts in a stop
Incomplete implementation of showing a warning when there alerts related to a stop.
Need more data (GTFS stops.txt table) to show the alerts for a stop
Fix T1113
Test Plan:
Check that GTFS realtime positions work.
Check that alerts are shown for a route/line.
Open a bus on the map and see that there is an icon showing the vehicle type
