Add item with multiple tabs/panels

[jrmi]

If you have a lot of items like card for drafting, you might want to have them all in the same screen but organized in different groups/categories. A tab item would hold other items like image or zone and could set the visibility of each items depending on the current tab. We could then add items to a tab and when we switch to another tab the items are replaced with the item of this new tab (if any).
