adapt checkboxListGroup and radioButtonListGroup to bootstrap 3.2

[peterfromearth]

until then you have to use following syntax

echo $form->checkboxListGroup($model, 'checkbox',array(
    'widgetOptions'=> array(
        'data'=>CHtml::listData(Checkbox::model()->findAll(),'id','name'),
        'htmlOptions'=>array(
            'template'=>'<div class="checkbox">{beginLabel}{input}{labelTitle}{endLabel}</div>',
            'labelOptions'=>array('class'=>''),
        ),
    ),
));
