User shouldn't be able Insert fields when onEditable option is false

[philmirez]

Set onEditable to false.

    $scope.obj = {
        data: json, 
        options: {
            mode: 'tree',
            onEditable: function(){return false;}
            }
     };

Click on the box [ ] to the left of a key and then select insert. Right now, a blank field and value are inserted. Warning signs are displayed without any capabilities to resolve since json is readonly.
