Replace title tag automatically with news title in the detailed view.

Calendar module does it for events details with the code below:

	// Adds the event title to the page title
	function ContentPostRender(&$content)
	{
		global $gCms;
		$module =& $gCms->modules['Calendar']['object'];
		if (isset($module->current_event_title))
		{
			$text = $module->current_event_title;
			if (function_exists('str_ireplace'))
			{
				$content = str_ireplace('<title>', '<title>'.$text. ' - ', $content);
			}
			else
			{
				$content = eregi_replace('<title>', '<title>'.$text. ' - ', $content);
			}
		}
	}
