## About The Pull Request
Basically goes through and puts some flat objects onto the floor plane.
Also puts blood back on the floor plane, since it seems like it used to
be but may have been moved mistakenly questionmark.
This means they will not be affected by Ambient Occlusion:

## Why It's Good For The Game
A lot of these "flat" things look really out of place because they're
secretly "floating" due to being on the wrong plane

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.
