necromanceranne 320185d1a4 Ensures that components can stop attack_self() proc code from running on energy guns if it would return COMSIG_CANCEL_ATTACK_CHAIN (#92019)
## About The Pull Request

What it says on the tin.

## Why It's Good For The Game

Should a component potentially want to override the behaviour of energy
guns attack_self() proc, it will not be able to prevent this code from
running without this check.

Datum Component System (DCS)

Concept

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 its arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
