@josephdadams can I remove the "messaging_client" socket event? Is it still required?

[josephdadams]

@MatteoGheza fine with me to remove messaging_client, I don't remember why I made it but pretty sure it had to do with the chat/messaging functions in the web tally viewer and any clients that supported it. But I think we redid those events in another way
