Added a new FleePlayerGoal, if an entity feel scared or threatened by the player. They run away at 1.5x speed. Also updated the system-chat examples to provide a more sequential list of messages.

- Added moveConflictingGoals function (to prevent duplicate goal priorities)
- Fixed FollowPlayerGoal to not clear the this.targetPlayer variable when stop() is called. This can be temporarily stopped due to a higher priority goal.
- Updated TALK priority to 2, and FOLLOW priority to 3, for maximum compatability across entities, without overriding their most important survival/attack goals.

- Refactored Goal Adding/Removing to make it more generic
- Added enum for Goal Priorities, since an entity can have both Talk and Follow goals at the same time.
- Updated Follow goal to no longer look at the player once they reach the player.
- Removed slowness status effect, replaced with Talk Goal

Simplifying character creation, to specify name and type in user message. Lowered chat bubble a bit. New improved user message for system-character prompt. Added lots of examples outputs for system-chat prompt.

Added goals for "FOLLOW" and "UNFOLLOW", so Mob Entity types will follow the player. Refactored some code, to make this cleaner. GPT 3.5 still struggles to output the behaviors correctly, so I updated to GPT 4 Turbo.
