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'); ";
