Update HtmlToolbarHelper.php

Try to make array from objects
This is useful for cases like 
class Date{
	private $time;
	public function setTime(){
		$this->time = time();
	}
}
class Name{
	private $first;
	public function setName(){
		$this->first = 'a1';
	}
}
$Art = new Object();
$Art->date = new Date();
$Art->name = new Name();
$Art->date->setTime();
$Art->name->setName();
