Golams

Implemented :

Entities :

 * Cartographer Golam (80%) -> can be given a naturally generated map (buried treasure, mansion or monument) by right clicking on the golam. Once it got a map, right-clicking on the golam with a golam core will :

 * Make the golam look in the direction of maps poi coordinates . If poi is not reachable, it will be the only action done (will have an animation later)
 * Make the golam move to the maps poi coordinates. (useful with buried treasures, the golam will reach the coordinates of the treasure and stand on the block above the chest)
