    Don't require duplicating conversation message signals on the viewer.
    
    Since we want GearyController to handle the effects of most user actions,
    we've had to duplicate ConversationMessage's signals on
    ConversationViewer and chain them down.
    
    Instead, add a message_added & message_removed signal to
    ConversationViewer and emit them as appropriate, then have
    GearyController connect to those and manually manage hooking/unhooking
    itself to ConversationMessage signals as instances are added/removed.
    
    Do this to the link clicked signal to start.
    
    * src/client/application/geary-controller.vala: Add on_message_added and
      on_message_removed handlers, connect them to the main window's
      ConversationViewer instance and added/remove the message's link click
      hander there.
    
    * src/client/conversation-viewer/conversation-viewer.vala: Add
      message_added and message_removed signals, hook them up as messages are
      added and removed. Remove link_selected signal and plumbing.
    
    * src/client/conversation-viewer/conversation-message.vala: Rename
      link_selected to link_activated to match GTK nomenclature better.
