对dede_sys_enum添加father字段，实现目的：在添加联动分类时，自动添加father的值。以500为分类界限。即：503的父类（father）为503,1001的father为1000。
主要修改的文件 stepselect_main.php文件。
解决： 修改有三处。
1.主要添加内容：
$father = intval(floor($evalue/500))*500;
2.修改内容：
$sql = "INSERT INTO `zuimoban_sys_enum`(`ename`,`evalue`,`egroup`,`disorder`,`issign`,`father`)
VALUES('$ename','$evalue','$egroup','$disorder','$issign','$father'); ";

function __addenum_save() { }
关于二级枚举的说明，为了节省查询速度，二级枚举是通过特殊算法生成的，原理为
凡是能被 500 整除的都是一级枚举，(500 * n) + 1 < em < 500 * (n+1) 为下级枚举
如：1000 的下级枚举对应的值为 1001,1002,1003...1499
对于 issign=1 的，表示这个类别只有一级枚举，则不受上面的算法限制
------------------------------------------------------------------------
更新算法:
新增二级枚举下添加"-N"自己类别选择,例如:
1001二级枚举下面的3级类目,则为1001-1,1001-2...
这时候需要issign=2
