[Guillaume Desmottes <gdesmott src gnome org>]

commit c3a3fdbca5129984d875b217d8204531ccf900ab

Date:   Tue Apr 10 13:15:07 2012 +0200

    implement empathy_tp_chat_get_members as a method on TpChat
    
    That means EmpathyTpChat doesn't have to implement the EmpathyContactList
    interface any more.
