Think of the children! adds a context menu option to toggle the display of unpublished content nodes.
There's not really a whole lot to describe, it just does what it says on the box.
Package includes a class inheriting from ApplicationEventHandler which hooks into the TreeControllerBase.MenuRendering event to smush a new menu item into the context menu.
The current state is pumped into localstorage to maintain the selection when the backoffice reloads.
Corrects a bug to ensure listening for the menuState.changed event only when the content section tree is active
