Ports https://github.com/tgstation/TerraGov-Marine-Corps/pull/3528
Credit goes to original coders. This PR makes large objects transparent
when something important is behind it.

For now the list of large objects and the things make them transparent
by using this component as follows:

Large objects:

- Trees
- Cranes
- Old shipping containers (new ones doesn't allow anything to go behind
it)

The things make them transparent:

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.
