      Defines all the widgets that each of the types of JS modal dialogs
      need (alerts, confirms and prompts). When we inflate the layout
      in JSModalDialogHolder we show hide the widgets we need as appropriate
      for the type of dialog we need to show.
      TODO(benm): Move this into the framework once we are integrated with the
      Android tree.
