Add a Group Chat.

I thought of this during a game when I can currently really need this, a group chat that is NOT coalition chat. It would be very nice to message a group of people in maps like 25p and 100p where communication is key, and so you don't have to message 5 people the same thing about a strategy or an event, when in this case you could just have a group chat and message them all at once and they can message everyone back at once too. It would really help.
