Title: Proper CLDR version identified and codebase updated against related CLDR SVN tag.

Issue #1602 is partially related to this PR. What action has been done for reaching results of this PR:

**1)** I've downloaded (svn checkout) following tags of CLDR SVN:

```
release-1-6
release-1-6-1
release-1-7
release-1-7-1
release-1-7-1-1
release-1-7-1-2
release-1-7-2
release-1-8
release-1-8-1
release-1-9
release-1-9-1
release-2-0
release-2-0-1
release-2-0-1-d01
release-2-0-d01
release-2-0-d02
release-21
release-21-0-1
release-21-0-1-d01-icu49rc
release-21-0-2
release-21-d01
release-21-d02
release-22
release-22-1
release-22-d01
release-22-d02
release-22-d03
release-22-d04
```

CLDR SVN tags are available here: http://www.unicode.org/repos/cldr/tags/

**2)** Then i've iterated through all of these versions of CLDR and executed `build cldr` command against each of them.

**3)** How to detect currently used CLDR version? Right, it could be easily detected through comparing diffs/patches.

Unfortunately i didn't manage to determine exact CLDR release where diff length would be zero. (In other words, no changes at all.)

But there are other interesting results:

— `release-21` and `release-22` doesn't fit at all to the currently used CLDR data (diff was very long).
— `release-1-9-1` and older doesn't fit to my requirements too (diff also was very long).
— More or less short patches were given by trying to build CLDR versions: release-2-0, release-2-0-1, release-2-0-1-d01, release-2-0-d01, release-2-0-d02.

**4)** I've thrown away everything but these five versions of CLDR. Then i've thrown away versions with `-d**` suffix because releases page (http://cldr.unicode.org/index/downloads) is not referring them at all (and it seems it's just a beta or transitional releases).

`release-2-0-1` is newer than `release-2-0` so i've decided to use it.

**5)** You can satisfy yourself by taking a look at the diff of this PR. Changes are very tiny without critical changes that may cause bugs.
