First feature implemented, autotiles

 Here is the big first feature implemented, I will start with the map editor and at this moment I want to make RM2K tilesets available for the tool.

Autotile positioning

• From 12 tiles generates 36 variations
• The variations are automatically placed in the editor depending on the place you are drawing

Right now it still uses RM2k tilsets but in the future it will allow to import whatever tile you want
