Draw transit vehicles as trolleybuses, cable cars, funiculars, gondolas and monorails

The transit layer knew five modes, so a trolleybus drew as a bus, a
funicular as a train and a coach as a city bus. The GTFS basic route types
are now modes of their own (trolleybus, cable_tram, monorail, funicular,
aerial_lift), each with an icon, colour, detection tier, card word, voice
name, speed ceiling and fleet model.

A vehicle record may carry its route's GTFS route_type as routeType. It
settles the mode after the feed's fleet hint and before its route hint, and
picks the finer model (a coach for 200, a high-speed set for 101) when the
type is a kind of the vehicle's mode. Retained history classifies epochs
through transitModeFor too, so trails join the live vehicle.

Route hints from each operator's routes.txt: Prague's trolleybus lines
(51-59, 232, 275) and Petrin funicular, and the trams, trolleybuses and
metro lines of Bucharest, Cluj-Napoca and Turin. A feed may also name
route corrections that outrank the route type: Le Havre's routes.txt types
its funicular (8-FUNI) as a bus, so it is corrected to a funicular.
