[geary/bug/728002-webkit2: 62/140] Fix attachments UI not ever being displayed.

[Michael Gratton <mjog src gnome org>]

commit 6171ff2ebd00534595ab9a8e04cf86f172fc01ce
Author: Michael James Gratton <mike vee net>

    Fix attachments UI not ever being displayed.
    
    * src/client/components/client-web-view.vala (ClientWebView): Make
      has_valid_height a GObject property so we can get notified about it
      changing.
    
    * src/client/conversation-viewer/conversation-email.vala
      (ConversationEmail::connect_message_view_signals): Fixed to listen to
      has-valid-height changing rather than the old WK1 load-status property.
    
    * ui/conversation-message.ui: Set body_container orientation to vertical
      so adding the attachments widget works as expected.
