Outline: add inspector hints to pages again

Some Scout versions ago, the inspector hints were added to the page
so that inspecting the page using browsers dev tool revealed the
model class and class id. This feature broke as the tree node logic
was separated from tree into the class TreeNode without moving
the function responsible for the inspector hints.
