Refactor pathfinding updates and add AccessReader support (#1183)

There was some extra bloat in the path graph updates.
Now the queue should also just run if it gets too big regardless.
Un-anchored physics objects are no longer a hard fail for pathfinding.
Add AccessReader support so open / close doors show up for pathfinding
AI also ensure they call the operator's shutdown when they're shutdown so that should cancel the pathfinding job.

I tried to split these into 2 commits but they were kinda coupled together
