Refactor of EntityChatData constructor (no need for playerName anymore). Fixed a bug which broadcasts death messages for any mob with a customName (now it must also have a character sheet)

Additional regressions caused by switching from UUID to player's display name (nick). Also, setting "born" and "death" timestamps, and no longer deleting chat data.

Limiting LEAD particles to 3, and move them further in front of the entity. Also scale LEAD particle smaller.

New animated lead particle (arrows pointing where they are going). New animated attack particles with random # of particles.

Small refactor to playerData args, and a fix to prevent "" blank player from being in every entitychatdata. It should only exist with migrated data. Also made the old legacy JSON properties disappear after saving this new data structure.

Large refactor of EntityChatData, EntityChatDataLight, and ChatDataManager. Separating these into smaller, individual files, to make it easier to maintain.

Don't force path aware entities to look at the target while navigating a path (this breaks their ability to jump)

Reduced # of waypoints to 6 to 20. moveToTarget() every call to tick(). Add particles for debugging LEAD behavior. Switched back to FuzzyTargeting for finding valid positions.

Limit waypoint locations to 45 degree angle from current direction. Remove FuzzyTargeting (since it finds things too close to the entity to be useful). Fixed non path aware to use custom LookControls.

Fixing crash when displaying message on LeadPlayerGoal, to run the generateMessage in a scheduler (after 1 tick), and not in the Goal's tick method.

New LEAD behavior, to guide a player to a random location (and show message when destination is reached). Updated unit tests to add new LEAD tests.
