Add option to hide the description

[TaqiyEddine-B]

When we have nothing to add in the desciption, we simply put noting in the filed "desciption" :

swipeSelector.setItems(
                new SwipeItem(0, "1", ""),
                new SwipeItem(1, "2", ""),
                new SwipeItem(2, "3", "")
);

but it's not an optimal solution, the ui is badly affected
