AutoPlacement event flows

AutoPlacement event flows are used by the AutoPlacementMgr to determine whether actors should be dynamically spawned without having to hardcode special logic into the executable.

Such event flows are executed by the same event flow engine but with a different environment: only the "AutoPlacement" pseudo-actor is available for actions and queries. Actions and queries are not mapped to AI system functions as with regular event flows, but are entirely handled by the AutoPlacement code.

A single event flow can be used to handle conditions for several actors (for example, AutoPlacement_Animal handles auto placement logic for all animal actors) and may be called several times, each time with a different actor name, which the event flow can check with the #EcoAreaActorName query. An actor will only be dynamically spawned if CreateData (and NearCreate?^[check]) is called.
