Refactor messages back to a single List<ChatMessage>, but now with a "name" attribute based on Player's display name. This will more easily allow for filtering the list of messages by player name, and also allow for more role playing (i.e. changing nick on a server can change your friendship / message history).

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

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.

- Added new LLM tests for UNFLEE
- Fixed certain behaviors from colliding with others (i.e. mutual exclusive ones)

- new junit test module
- 4 initial tests for attack, follow, and flee
- improved regex to support <behavior> or *behavior*
- improved message cleaning
- refactor of HTTP requests to remove some Minecraft and Fabric specific imports
