map making

[jmlima]

Well, in parts:

- You cannot add buildings to an existing map. In fact, you cannot add any new terrain, or edit the existing. All you can do with the submap is to chop bits of a larger master map.

- To create your own building graphics , is simply a matter of replacing the tiles shown on the 'Map' folder, have a look in the '2dTerrain100' and '2dTerrain50' files.
