Prevent city-name abbreviations

[waldoj]

The function in use to standardize addresses has the unfortunate habit of shortening city names. "Falls Church" becomes "Fls Church." This is incorrect and confusing. Figure out how to prevent this from happening.

Worst-case, run the address-standardization function only on street_1, but that's going to prevent standardization of "city, state ZIP".

I've starting by removing the problematic abbreviations (e.g., the Falls => Fls mapping). Let's see if that approach works.
