Light Rail for All Trams

Every tram can now leave the tram network and run on railway tracks, just like the vanilla tram-trains. Works with vanilla trams, trams from other mods and future ones: trams are picked by their properties, never by a list. Settings: which trams (all / electric only / non-electric only), minimum year, passenger and/or cargo. Trams can stop at regular railway stations. Electric trams need electrified railway (catenary). Removing the mod from a running game can break tram lines routed over railway tracks.
