broken url

[bbenno]

The README's url referencing Unicode.org's CLDR repository is dead.

It actually seems that also the internal references are corrupted:

$ rails import:country_select LOCALE=de
... getting the HTML file for locale 'de'
[!] Invalid locale name 'es'! Not found in CLDR (404 Not Found)

I don't know what the original content of www.unicode.org/cldr/data/charts/summary/root.html was but I would suggest that it was moved to https://unicode-org.github.io/cldr-staging/charts/37/summary/root.html
