getid3_lib::array_min finds max instead of min

Both getid3_lib::array_min and getid3_lib::array_max seem to find array max.

This might be a copy/paste mistake. I assume array_max was copied, variables were renamed, but the condition was not changed.

	/**
	 * @param array $arraydata
	 * @param bool  $returnkey
	 *
	 * @return int|false
	 */
	public static function array_max($arraydata, $returnkey=false) {
		$maxvalue = false;
		$maxkey = false;
		foreach ($arraydata as $key => $value) {
			if (!is_array($value)) {
				if ($value > $maxvalue) {
					$maxvalue = $value;
					$maxkey = $key;
				}
			}
		}
		return ($returnkey ? $maxkey : $maxvalue);
	}

	/**
	 * @param array $arraydata
	 * @param bool  $returnkey
	 *
	 * @return int|false
	 */
	public static function array_min($arraydata, $returnkey=false) {
		$minvalue = false;
		$minkey = false;
		foreach ($arraydata as $key => $value) {
			if (!is_array($value)) {
				if ($value > $minvalue) {
					$minvalue = $value;
					$minkey = $key;
				}
			}
		}
		return ($returnkey ? $minkey : $minvalue);
}

Note that it's not enough to change > to <. The initial value of minvalue needs to be changed too, otherwise array_min could return false.
