Secondary locale lookup

[jcrugzz]

If the given locale doesn't exist, check the more generic version of the locale to see if a more general build is applicable.

LGTM 👍

Note about IETF language code Vs BCP47 country code

What about just en? Since we are just using the first part below shouldn't that be valid?

@indexzero yea but that wouldn't hit this retry case, that would have been what was requested initially. this would handle fallback from en-US to en or es-ES to es

If we do this now anyways, couldn't we also supply an array of locales and go from [0] to [last] on the array to fetch locales. This solves some of the internal issues we have with reading locales from package.json, checking indexOf against that and then providing the right locale. Would be awesome and eliminate tons of optional code if we can just supply es-ES,es-US,en-US Similarly, browser ship a comma separated string to get a response from the server in a preferred locale.
