Bug 18112: Add street type to self reg/self mod form

1. Add some values to the ROADTYPE authorized value
2. Go to PatronSelfRegistrationBorrowerUnwantedField and make sure
   streettype is NOT checked
3. Go the self reg form, no street type field
4. Apply patch
5. Check the self reg form, streettype should be there with all the
   options defined in ROADTYPE a.v.
6. Check the self modification form, street type should be there.
7. Make sure PatronSelfRegistrationBorrowerUnwantedField and
   PatronSelfModificationBorrowerUnwantedField hide the field correctly.
8. Make sure PatronSelfRegistrationBorrowerMandatoryField properly makes
   the field required.
