Update Babel to 1.3.

Babel Changelog
===============

Version 1.3
-----------

(bugfix release, released on July 29th 2013)

- Fixed a bug in likely-subtag resolving for some common locales.
  This primarily makes ``zh_CN`` work again which was broken
  due to how it was defined in the likely subtags combined with
  our broken resolving.  This fixes #37.
- Fixed a bug that caused pybabel to break when writing to stdout
  on Python 3.
- Removed a stray print that was causing issues when writing to
  stdout for message catalogs.

Version 1.2
-----------

(bugfix release, released on July 27th 2013)

- Included all tests in the tarball.  Previously the include
  skipped past recursive folders.
- Changed how tests are invoked and added separate standalone
  test command.  This simplifies testing of the package for
  linux distributors.

Version 1.1
-----------

(bugfix release, released on July 27th 2013)

- added dummy version requirements for pytz so that it installs
  on pip 1.4.
- Included tests in the tarball.
