show icon for new messages in roster too, even if a chat with the acct is already open
it would be nice if the roster would show new messages even if you already have a chatwindow opened with that account, until you acctually read the message. atm only the chat window shows, that you have a new message. now take this for example: you have a chatwindow opened with multiple tabs, but it is covered by another window, but the roster isn't. if you look in the taskbar, you see, that you have a new message. but in the roster, nothing is shown. if you could see in the roster, who sent you the message, you would know immediately. when the message is read, the title of the chat window changes back so that it doesn't contain * or [n] and the icon in the roster for a new message disappears.
at the moment the icon for new messages is only shown in the roster, if you don't have a chat open with the person who sent the message.
