Add printing capabilities.

Add printing capabilities using the javax.print package and the BufferedImage generated from the Graphics class.

Currently works for mazes of up to size 85x85, anything larger is blank except for the pink start and end squares. Need to work to fix this.

Works fine for mazes that are not square, so this is a good step in the right direction.

Need to scale up the maze so that it takes up more room on the page and is larger on the printed sheet.
