Best viewed without space changes... or maybe it doesn't matter any more.
Debug setting OtherChatsTornOff added.
Added Open new IMs in separate floaters checkbox to Adv. Chat.
Moved Show group name in chat to the right column on top of Adv. Chat panel.
So how's this work?
Two ways.. 1. The user opens a chat; 2. A chat is started from another party to the user.
In 1, we open the chat in a separate floater and focus the floater.
In 2, we check if there is a floater currently in focus before opening the chat
if so, we minimize the floater, setting focus back to whatever floater the user was focused on;
if not, we leave the new chat floater open and focused.
Note that this will NOT alter the default behavior at all, we can't be having that.
