Subject: [PATCH] Improve Player chat API handling
Properly split up the chat and command handling to reflect the server now
having separate packets for both, and the client always using the correct packet. Text
from a chat packet should never be parsed into a command, even if it starts with the `/`
character.
Add a missing async catcher and improve Spigot's async catcher error message.
