Added a decoration tileset, and replaced every tileset with its 16x16 version.
Grass now uses the Decoration tileset.
Tilesets are 16x16, to scale them we need to get rid of the ugly image smoothing. Too bad there isn't really one solution for this..
Made lots of changes to the tileset!
You don't have to specify a color anymore. So I got rid of all that code! Sprites only from now on!
Whenever you enter a door, you get the next tile on the tileset.
Walls now generate with random bricks.
Wrote the ugliest but also the most awesome piece of code. It connects walls with eachother and defines the correct tiles for them.
