Now the below behaviours are allowed.
```Go
var id int64
var name string
has, err := engine.Table(&user).Cols("id", "name").Get(&id, &name)
// SELECT id, name FROM user LIMIT 1
```
```Go
rows, err := engine.Cols("name", "age").Rows(&User{Name:name})
// SELECT * FROM user
defer rows.Close()
for rows.Next() {
var name string
var age int
err = rows.Scan(&name, &age)
}
```

Now you can use delete like this:
```
orm.Table("my_table").Where("id=?",1).Delete()
```

#1864 Export tag identifier so we can change that form `xorm` to others
This will be useful when in some migration scenarios such as migrate `sqlx` to `xorm`, the former uses `db` as the identifier and has a very simple rule which can be covered by xorm parser rules
