PathfindingLagFix

This modifies the Bracken AI (and others soon) to prevent it from causing a large stutter every 200ms in some situations, by spreading the load of checking hundreds of paths over multiple frames.

Details

The EnemyAI.ChooseFarthestNodeFromPosition() function could end up checking 180+ nav mesh nodes for accessibility, if most or none of them were accessible. This could happen if the enemy was not on the nav mesh, or if the function call required line of sight and players were blocking most of the map from access.
- This would occur for the Bracken if it spawned outside since it has no outside nodes, or if the bracken was in a dead end with a player watching the exit.
- There may be other cases where this type of issue could occur, but currently this mod only patches the Bracken. Please report any cases to investigate with steps to reproduce the lag.
