Unicode CLDR Version 26

I'm currently working for #69 because #69 is a critical issue for Japanese.

This PR is updating Unicode CLDR to version 26 simply. #69 will not resolve by this change, but I'd like to get done this first to make upstream data as up-to-date as possible. The release note of CLDR version 26 as follows.

* http://unicode-inc.blogspot.jp/2014/09/cldr-version-26-released.html
* http://cldr.unicode.org/index/downloads/cldr-26

The testing by `npm test` might be fails, but I think that be not due to this change.

It includes many locale data updates. Please checkout my branch manually if you're with slow browser.
