    Convert ConversationWebView HML CSS file to a resource, remove theme dir.
    
    * src/client/application/geary-application.vala
      (GearyApplication::read_theme_file): Renamed to ::read_resource, do the
      lookup on a GResource instead of from the file system.
      (GearyApplication::get_ui_file): Remove unused method.
    
    * src/client/conversation-viewer/conversation-web-view.vala
      (ConversationWebView): Chase CSS file rename and load method.
    
    * theming/CMakeLists.txt: Removed, no longer needed.
    
    * theming/message-viewer.css: Moved to ui/conversation-web-view.css.
    
    * ui/CMakeLists.txt: Add conversation-web-view.css resource.
    
    * CMakeLists.txt: Remove theming include.
    
    * src/client/application/geary-application.vala :
