+1. `clone()` helper is now passed full HTML element dragged, not an event on `grid-stack-item-content` so you can clone or set attr at the top.
 2. use any class/structure you want for side panel items (see two.html)
 3. `GridStack.setupDragIn()` now support associating a `GridStackWidget` for each sidepanel that will be used to define what to create on drop!
 4. if no `GridStackWidget` is defined, the helper will now be inserted as is, and NOT original sidepanel item.
