Change BeanListHandler to be able to handle to list of the bean's super class or interface
------------------------------------------------------------------------------------------

                 Key: DBUTILS-82
                 URL: https://issues.apache.org/jira/browse/DBUTILS-82
             Project: Commons DbUtils
          Issue Type: Improvement
    Affects Versions: 1.3
            Reporter: Kenshi Toriumi
            Priority: Minor


BeanListHandler handles to list of the bean class itself only.
If want list of the bean's base class or interface, two steps of cast are needed.
{code:borderStyle=solid}
// Bean is super class or interface of BeanImpl
BeanListHandler<BeanImpl> blh = new BeanListHandler<BeanImpl>(BeanImpl.class);
List<BeanImpl> beanImplList = queryRunner.query(sql, blh);
List<Bean> beanList = (List<Bean>) ((List<?>) beanImplList);
{code}

I want to change BeanListHandler to  be able to handle to list of the bean's super class or
interface;
{code:borderStyle=solid}
// Bean is super class or interface of BeanImpl
BeanListHandler<Bean> blh = new BeanListHandler<Bean>(BeanImpl.class);
List<Bean> beanList = queryRunner.query(sql, blh);
for (Bean bean : beanList) {
}
{code}
