Expose getFindByTagsCriteria method

[ashkarpetin]

In my web application i'm using CActiveDataProvider with filtering. I also wanted to filter records by tags but can't find a solution to do it with behavior out of the box. Dirrrrrty hack to show idea is:

public function getFindByTagsCriteriaExt($tags) {
        return $this->getFindByTagsCriteria($this->toTagsArray($tags));
    }

And in my controller code merge $criteria->mergeWith(Repo::model()->getFindByTagsCriteriaExt('yii, php')). The problem toTagsArray($tags) is used in taggedWith method not in getFindByTagsCriteria.
