ICEfinder per Tobias Hellbusch

This add-on finds out what type of ICE train (e.g. ICE 3) is assigned to a particular train number (e.g. ICE 1069, found in the schedules) using the information from the database over at https://www.fernbahn.de/datenbank.

It neatly integrates into the DB search results like this:
without extension: "ICE 1069 nach München Hbf Gl.5-10"
with extension: "ICE 1069 [ICE 3] nach München Hbf Gl.5-10"
