## About The Pull Request
Flamethrower exploding when shot was handled by hit_reaction previously,
and will now use the generic bullet_intercepting component. Also adds
handling for multiple projectile types in the bullet_intercepting
component, as well as a check for whether the object currently can block
bullets. Should have no gameplay changes.
## Why It's Good For The Game
closes#81863 , they said it'd be better consistency
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.
