Level node connections

I had planned the structure of the game world on paper (that was a while ago) and finally wrote the data for level node connections. It took about one hour. It's not that the game world of Kaduria is big, it's actually not, but there were some number of level themes to connect so it didn't happen fast. It's not over though for the connections. I still have to write the actual entrance creation code based on that data. It's not easy, because there are special entrance types that need to be there in the level theme. I'm not talking about the stairs itself, but the places stairs or other entrance types are sometimes hidden.
