[empathy/gnome-3-2: 2/7] TpChat: track subject and title explicitly.

[Will Thompson <wjt src gnome org>]

commit 8e32f31c9bb13885ff23ee4ef11787f82886ce2e
Author: Will Thompson <will thompson collabora co uk>
Date:   Thu Sep 8 10:48:03 2011 +0100

    TpChat: track subject and title explicitly.
    
    This will allow us to also use the new API (and, ultimately, delete
    the Telepathy.Properties code cleanly).
