giomba 6137f21b48 implemented transition mode 
if transition_mode pin is high, then images are shown continuosly
(eg the next image is shown as soon as the next_image button is pressed)
but if transition_mode pin is low, then, when you press the button, the
current image disappears, and the next one appears when you press the
button again
