Display error messages inside a conversation

if the error has the same id as a sent message, it will be displayed
    with a cross where there is usually a checkmark (ack), and the
    received error will be appended to the message, in red.
if it does not have a know id, it will be added as another message to
    the conversation, without a nick, and in red.
