Bug: Framerate degraded by NPCThink

The NPCThink function for my Agent has to interrogate the world to get all the preconditions for the world state. Unfortunately, this destroys the frame rate because it has to traverse the full list of level entities, and the think function is called every frame.

Fix: Limit the drop into the interrogation function to only happen every 2 seconds – the state will not change so much in 2 seconds to have any effect on the performance of the planner, and this fix improves the frame rate tremendously.
