[REQUEST] Allow actors in the Scene Panel to be colored

I am currently dealing with a scene where a lot of actors that I frequently need to interact with have similar names.
It would be really useful and remove a ton of friction if I could assign these actors a color in the scene tree for easier recognition.

I think the easiest way of doing that would be to render the names of the actors in the selected color, though maybe that's a bit hard to see?

This would really be a huge improvement to working with huge scene trees and it would remove those ~2 second breaks of having to search for the right actor by name from my workflow.
