***********************************************************************************************************
        @type                  :  'P'  代表存储过程 , 'F' 代表存储过程，如果需要可以扩展其它对象

    2013-05-13           Kerry                 V01.00.01             排除系统存储过程和系统函数的授权处理
    2013-05-14           Kerry                 V01.00.02             增加判断,如果某个存储过程已经赋予权限
                                                                     则不做任何操作
