Bees, wither, wandering trade, and error handling

See merge request !28

Improved error handling to prevent broken "..." pending chat status. (HTTP and message processing is more protected). Removed randomized error messages from chat history (so it doesn't break the chat history when an error is shown)

- Broadcasting and receiving chat messages now ignores if the UUID is valid (to keep data synced)
- Bees no longer forget their chat data when entering/leaving hives (writeNbt & readNbt modified)

Added many new speaking styles (minimalist, nerdy, stupid, gen-z, old timer, boomer, etc...). - Removed a few variables from the chat context (creative mode, hardcore, difficulty). Improved variety of examples in chat prompt.

Fixed unit tests for friendship (some were being skipped). Updated unit tests output JSON (for comparison)

- Modified system-chat prompt a bit, to make friendship always lower when attacked, added an UNFLEE example

Chat messages are now displayed in chat bubbles above players heads

Icon updates

See merge request !26

Fixing regression which caused uncleaned messages (i.e. with behaviors) to be broadcast to players. This is fixed by adding only the cleaned message, and then updating the previousMessage history with the original/uncleaned message.

Changed UV coordinates slightly for bottom right of the icon, to not overlap the front of the skin's hand. Updating ICONS.md assets to use new UV coordinates.

New command `/creaturechat chatbubbles set <on | off>` to show or hide player chat messages in bubbles

Seperated Player and Entity message broadcasts (different packets for simplicity). Removed extra message broadcast (which was unnecessary).
