- FollowerAI properly resumes follow after evading. - Removed duplicated getters from CreatureAI (IsEscorted vs IsEscortNPC), they were used to do the same thing - FollowerAI properly assists in combat. - FollowerAI properly despawns if quest is abandoned. - FollowerAI now supports dynamic respawning for escort NPCs.
