Added all the necissary changes to guild the gui.

To fit the structure of the gui program I had to move:
GameMoves.java
Maze.java
Prolog2JavaGameMovesTranser.java
maze.pl
From the default package to it's own jpl package.
All the buttons are working minus the fog of war check box.
Fixed Integration Issues

-Fixed printing issues when multiple items are entering or leaving a square
-Fixed the gold index ArrayOutOfBounds problem
-Fixed a build problem with all java source in the jpl package
-Added the isHere() method in the Agent file
