Chat protocol rewrite (#5117)

* New TOCLIENT_CHAT_MESSAGE packet

* Rename old packet to TOCLIENT_CHAT_MESSAGE_OLD for compat
* Handle TOCLIENT_CHAT_MESSAGE new structure client side
* Client chat queue should use a specific object
* SendChatMessage: use the right packet depending on protocol version (not complete yet)
* Add chatmessage(type) objects and handle them client side (partially)
* Use ChatMessage instead of std::wstring server side

* Update with timestamp support
