Fixed issues in last pull request.

Replaced all of the thrown exceptions with try catch statements.

Cleaned up the MouseEvent methods. (The MouseEvent methods for the ActionListener for the frames buttons will not work for the jPanel.  ActionListener does not work with jPanel's so you have to use a MouseListener and MouseAdapter and define its own MouseEvent methods).

When the boardPanel is clicked it now returns the coordinates where clicked which are stored as int x and y and printed to the console.
