Adding a tileset

Guess who learned about tilesets today!!! Ok, the last post I said that I didn't see the lost code as a loss, because I got to practice how to deal with procedural building. But what I didn't deal with was to add a tileset, right now I have a bunch of rules to have a congruent environment. Next step, add some variations on the tiles. 

I'm using this tileset. I like the work of that guy
