Follow widget parameters

- item (integer): to separate follows between different items.
```<?= Follows::widget(['item' => 1]) ?>```
```<?= Follows::widget(['item' => $model->id]) ?>```

default value for item is 0
- service (integer): to separate follows between various item types.
```<?= Folloes::widget(['service' => 1, 'item' => $model->id]) ?>```

    'item' => $model->id,
    'color' => 'yellow',
    'view_file' => Yii::getAlias('@frontend') . '/views/follow/widget.php'
]) ?>```

you can use these variables in your customized view:
