Title: added reverse order for admin_order_field

after adding this you can setup something like this:

```
def age_in_years(self):
return # age calculated via DateField self.date_of_birth
age_in_years.admin_order_field = '-date_of_birth'
```

the '-' at the beginning of '-date_of_birth' indicates the reverse order in the changelist.
