- moved main polyobject array into FLevelLocals and simplified the setup process to not depend on P_SpawnMapThing.

Since the SpawnedThings array is still available when polyobjects are spawned it makes no sense to create an expensive linked list in P_SpawnMapThing.
This can be done far better by scanning through the array again and collect all matching items in a second array.
