[TYPO3-ect] lib div feature request - debug for php5

[Steve Ryan]

Hi Elmar,
  any chance to include the following function in tx_lib_object. Since
php5, using debug on an array containing a tx_lib_object subclass causes
and exception because it cannot be converted to string.

	function __toString() {
		ob_start();
		$this->dump();
		$content=ob_get_contents();
		ob_end_clean();
		return $content;
	}

thanks

Steve Ryan
