removed final from isVisible to support more elegant use of cases that had to be done like:

		WebMarkupContainer resultsTableHeader = new WebMarkupContainer("resultsHeader")
		{
			public void render()
			{
				setVisible(searchModel.hasResults());
				super.render();
			}
		};

could now be done like:

		WebMarkupContainer resultsTableHeader = new WebMarkupContainer("resultsHeader")
		{
			public boolean isVisible()
			{
				return searchModel.hasResults();
			}
		};
