Show delayed messages in group chat rooms

[GoogleCodeExporter]

If you connect to an existing chat room, the previous messages are displayed, 
with the exception of the ones emitted by the connected user.
This is because, in code, we exclude messages sent by the connected user, even 
delayed ones.
However, delayed messages by the connected user should be displayed to show the 
context of the conversation (imagine a dialogue with one peer not speaking!).
When opening a chat room, the delayed messages must be shown completely.
