Reverse Lookup Zip -> Country

[daspecster]

In theory, we could return a list of values based on a postal code that's entered.

I'm doing something similar to this with the Ziptastic API in an app I'm building at work; it queries the API multiple times until it finds the first likely candidate. This requires a list of country codes in order of priority... I like the idea of returning multiple results, but it might be nice for the API to optionally do the above as well.
