更改osworkflow支持hibernate3[6]

propertyset更改方案：

propertyset从CVS上获取最新代码，更改对应hibernate包内的所有引入的hibernate2改为hibernate3包。

对于osworkflow从cvs上下载的代码更改HibernateWorkflowStore

添加两个方法

// add find method for this class by yunguang

       public List find(String queryString) throws StoreException {

              Query queryObject = session.createQuery(queryString);

              return queryObject.list();

       }

       public List find(String queryString, Object value) throws StoreException {

              Query queryObject = session.createQuery(queryString);

              queryObject.setParameter(0, value);

              return queryObject.list();
