+	 * Wrapper for _getFilename (original "getFileName" renamed) that extends the original functionality in two ways:
+	 *   1. external resources can be included by specifying a url (e.g. http://ajax.googleapis.com/ajax/libs/prototype/1.6.0.3/prototype.js)
+	 *   2. local resources can include a query part (e.g. fileadmin/lib.js?version=1)
+	 *
+	 * If the parameter is an absolute url (starting with a protocol specification (e.g. "http://") or a shash ("/")) it will be returned unaltered.
+	 * Otherwise, the parameter value will be split into a url and an optional query part (?...), and _getFileName will be called with url as parameter.
+	 * If the result of this call is non-empty the query part (if any) will be appended to form the final result.
+	 *
+	 * @param	string		Url or Typoscript "resource" data type value.
+	 * @return	string		Url (possibly expanded from Typoscript resource)
+	 * @see _getFileName()
