Add method to get the clickable area of a TileObject

getClickbox returns an AWT Area object which corresponds to theclickable area of a GameObject, GroundObject, DecorativeObject or WallObject.

getClickbox for ItemLayers isn't implemented, since I haven't looked into how clickabilty works for items on the ground in the client.
