should fix #618 and #597

oldIndex was changed first by with the item being dragged, but also by the drag event of the parent (which should be avoided when we are not using the drag-handle)

Added onPickup event.

useful for providing the user with a visual, auditory or tactile indication,
in case a delay was enabled.

Remove Polymer from bower dependencies

Fix to knockout sorting when dragging item index 1 to 0.
