ECS: Investigate usage with UI

[christopher-buss]

Right now hooking up to UI code is... interesting. We could potentially look into setting up some sort of useECS hook for components. @Inctus was interested in this.

I'm fine with a useQuery(...) to update when a query changes (entity added or removed)

@RigidStudios could you explain a little more what you're thinking? I'm not perfectly understanding what an implementation would look like.

You should speak to @Inctus m about this since he originally requested this.
