Title: Tiny improvement on render() method in Magento\Backend\Block\Widget\Grid\Column\Ren...

...derer\Concat which allows now calls to any method on a model. Which is a huge win!

Configuration in adminhtml grid can look like this:

```php
$this->addColumn('product_price', array(
'header' => __('RRP incl. Tax
Sales Prices incl. Tax'),
'getter' => ['returnProductPrice', 'getProductFinalPrice'],
'align' => 'right',
'type' => 'concat',
'separator' => '
',
));
```

or this

```php
$this->addColumn('product_price2', array(
'header' => __('RRP incl. Tax
SP incl. Tax'),
'index' => ['product_price', 'product_final_price'],
'align' => 'right',
'type' => 'concat',
'separator' => '
',
));
```

No tests added ...

Thanks for merging :-)
