Bug 21144: Add ROADTYPE to default authorised values categories

The ROADTYPE category was missing from the default list of

- Apply patch and run database update
- Verify ROADTYPE is now listed
- Add an entry, for example: AV = Avenue
- Add or edit a patron, verify a pull down with your entry
  shows on the form.
