## About The Pull Request
All investigate logs start with [src], which can be any atom. So
sometimes names and items get printed twice. Adds ckeys to the
investigate_logs of living mobs.

## Why It's Good For The Game
Better logging, includes the ckey for living mobs in investigate logs,
and fixes some investigate_death logs that weren't properly attributed
to mobs.
## Changelog
🆑 Tattle
admin: investigate logs include ckey of source (if applicable)

Loosely adapted from /vg/. This is an entity component system for adding behaviours to datums when inheritance doesn't quite cut it. By using signals and events instead of direct inheritance, you can inject behaviours without hacky overloads. It requires a different method of thinking, but is not hard to use correctly. If a behaviour can have application across more than one thing. Make it generic, make it a component. Atom/mob/obj event? Give it a signal, and forward it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
