Include Needs Zip?

[maxwell]

Hi!

Just wanted to see if there was any interest in building out a "Requires Zip?" method, as a bunch of random countries don't have a postal code to speak of.

If this will be implemented, please don't use the word "zip", but postal code.

Some countries don't have postal codes, but even less have a Zone Improvement Plan :) (To my knowledge only the US and the Philippines have "ZIP codes")

I am good with adding any country related info that we have a reliable source of information for.

It would probably be named postal code but have a zip method aliased for people who are use to postal codes being called zip codes.

I've implemented this in #156
