I've spent some time in Dubrovnik so I'm familliar with the city quite well. I've added the routes by my own knowledge. Since the city was already well-mapped, I didn't need to draw any new ways for bus routes.
I wasn't sure about lines 1A and 1C, though, so I left these alone. Also, I could remember the exact location of only some of the bus stop, so a very large number of them is still missing.
