Duplicate field names after stripping '_id' suffix
That was an awesome response time! :-) Thanks so much!
 NP! I really appreciate the bug report.

For reasons that are beyond me, I'm working on a database that often has fields which have the same name except for the `_id` part at the end, that is one called e.g. `language` and one `language_id`. Generating models for this table using pwiz gives me model definitions like:

```
language = CharField()
language = IntegerField(db_column='language_id')
```

Other than that, amazing how little tweaking I had to do! Thank you for the awesome ORM!
