[10358] A small spoon of changes and cleanup for WaypointMovementGenerator
* Initialization to ensure destination is always set (prevent evade problem) * Simplify how behavior for node is processed, incl fix MovementInform script call (based on idea/past code from Quriq14) * Make sure last node is also processed correct (DB script for last node will now work as expected) As usual if any problems occur, you can call our toll free customer support number.
