Add item ID to dev mode lab

It would be nice to have the item id in the right-click menu, like with columns to help playing around with the api.

Instead of having to get all the items name and id to copy the id and test mutations/queries I could just copy paste the id. (a copy icon would be nice too, since we already have to use the mouse to open the submenu)
