Data loading still not consistent: what I see after running the scripts

**This is not meant for merging.** I want to show what I see after updating to the current `master`, and running the 4 scripts listed in the README:

```
python scraper.py
python layer_with_csv.py
python layer_with_usa_contacts.py
python keywords_from_fr.py
```

Changes which look like bugs:

- [ ] Removed keywords for the DHS: Office of Inspector General
- [ ] Removed keywords for the DOC: International Trade Administration, Office of the Secretary
- [ ] New keywords for the DOI: Office of the Secretary
- [ ] Removed keywords for the DOT: Maritime Administration
- [ ] Removed keywords, `usa_id`, `abbreviation` and `description` for the DOT: Surface Transportation Board
- [ ] New keywords for the DOD: Office of Inspector General
- [ ] New keywords for the FMC (Federal Maritime Commission)
- [ ] New keywords for the STB (Surface Transportation Board)
- [ ] New keywords for the USITC (US International Trade Commission)
- [ ] The `top_level` field for the USPS went from `true` to `false`.

The STB appearing as both its own agency, and a DOT office, is clearly one of the issues. (But the [ITA](http://www.ita.doc.gov/foia/) and [ITC](http://www.usitc.gov/secretary/foia/index.htm) are two different groups.)

More normal-looking changes, but maybe not:

- [ ] An additional semicolon on a Copyright Office title
- [ ] Removed one keyword for the EPA: `poison prevention`
