Splits the restrained() proc into component traits: TRAIT_HANDS_BLOCKED for the general inability to use hands and TRAIT_RESTRAINED for the more specific condition that permits arrests.
Code moved away from the update_mobility() proc so it doesn't have to wait for an update, instead changing based on events. The idea is to eventually kill that proc.
Wrapper proc added for setting the handcuffed value so we can react to the event of it changing.
Kills the RestrainedClickOn() proc. That is now just an UnarmedAttack(), in where the ability to use hands can be checked. Monkeys keep their bite attack and humans their self-examine.
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 it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
See this thread for an introduction to the system as a whole.
