Object / Material Indices Panel
When working with ID Masks in the Nodes Editor, is hard to follow track
of which objects/materials have which ID.
This adds a panel on the sidebar when an ID Mask node is selected.
The active object is highlighted between [square brackets] On the Nodes
Editor's sidebar, when an ID Mask node is selected.
