Eeditable with model many_many

[vvillar21]

Hi, sorry for my english, wanted to give you a few lines of code to the extent contemplated a model of many to many , modify the EEditableColumn.php from line 48 when you give value to editable_id :

        if (is_array($keyValue)){
            $idEditable = "";
            foreach ($keyValue as $element) {   

                if ($element === end($keyValue))
                    $idEditable .= $element;
                else
                    $idEditable .= $element."_";

            }           
            $options['editable_id'] = $idEditable;
        }else{
            $options['editable_id'] = $keyValue;
        }

I hope you work for someone else , Greetings
