Subject: [PATCH] Class only PID's trolleybus lines as trolleybuses, and name
 the new modes in the plural for voice

PID's routes.txt types lines 51, 52, 53, 58, 59, 232 and 275 as
trolleybuses (route type 11); the rest of 50 to 59 stay buses, as before.
Voice now also knows trolleybuses, gondolas, cable cars, funiculars and
monorails.
