Concept Proof - Pacman LISP + JAVA

I have been doing some tests to see if the Java and Lisp would really work good together to the project using the library abcl. I had pretty good results, but probably I will have some trouble to convert java arrays in lisp lists and with the old design patterns adopted in the Open Source PACMAN. Although, it is part of the process of learning. This project already has "smart" ghosts that are unable to turn back in the path. I made some changes in the code/design and add one lisp function to control the Pacman. With the human behavior of "lose in a hurry" It is going randomly and also it is not allowed to turn back in the path.
