su_image_carousel: images not really “rotating” …

The “slider” generated by su_image_carousel does not appear like a real “carousel” but more like a lift that slowly goes from ground-floor to the roof and then plummets back 🙂

The old code su_carouselshows the images like
1–2–3–4–5–1–2–3–5–1–2–3–4–5…
which is kind of “going round”.

With the new code su_image_carousel it goes like
1–2–3–4–5–4321–2–3–4–5–4321-…
which is more a there and back.

I’d prefer the old behaviour as it looks way smoother …
