Makes it so deadchat control alerts ghosts when they can input another command. Also rounds the seconds values in the to_chat messages for deadchat control up, so they don't have a decimal point.
You don't have to keep trying to input something to see if the cooldown has expired yet. Removing the decimal point looks cleaner.
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.
