      an inline part has been loaded by the web view.
      (ClientWebView::handle_cid_request): Fire new signal when a part is
      loaded.
    
    * src/client/conversation-viewer/conversation-email.vala
      (ConversationEmail::connect_message_view_signals): Hook up new signal.
    
    * src/client/conversation-viewer/conversation-message.vala
      (ConversationMessage): Remove now-unesed attachment_displayed_inline signal.
