修改DZ7.2论坛程序原功能允许对回复进行热度评价
DZ 7.2自带的热度评价只对主题有效，而无法对回复进行评价。这里的修改可以让论坛对回复也进行热度评价
后台数据库管理里面运行SQL语句ALTER TABLE `cdb_posts` ADD `recommends` smallint(6) DEFAULT '0' NOT NULL;
ALTER TABLE `cdb_posts` ADD `recommend_add` smallint(6) DEFAULT '0' NOT NULL;
ALTER TABLE `cdb_posts` ADD `recommend_sub` smallint(6) DEFAULT '0' NOT NULL;
CREATE TABLE `cdb_postrecommend` (
`pid` mediumint(8) unsigned NOT NULL,
`recommenduid` mediumint(8) unsigned NOT NULL default '0',
`dateline` int(10) unsigned NOT NULL default '0',
KEY `pid` (`pid`),
KEY `uid` (`recommenduid`)
