added images to the GUI. The Seat buttons are now image icons, button text is no longer there but saved in tooltip text if needed. I will add different colored seat icons for taken (non available) seats. 
i have added "images" folder to the project. This is needed when we execute from jar file later to properly show images and sounds.
