Adds a list of train stops next to the locomotive UI with the stops sorted so that any with rich text icons in their name are ordered the same as if those icons were in your inventory / crafting menu.

You can click the stops to add them to the current train's schedule.

This is a proof-of-concept for a suggestion in the Factorio forums: https://forums.factorio.com/viewtopic.php?f=6&t=97719
