Update babel to 0.9.3.

Version 0.9.3
http://svn.edgewall.org/repos/babel/tags/0.9.3/
(Jul 9 2008, from branches/stable/0.9.x)

 * Fixed invalid message extraction methods causing an UnboundLocalError.
 * Extraction method specification can now use a dot instead of the colon to
   separate module and function name (ticket #105).
 * Fixed message catalog compilation for locales with more than two plural
   forms (ticket #95).
 * Fixed compilation of message catalogs for locales with more than two plural
   forms where the translations were empty (ticket #97).
 * The stripping of the comment tags in comments is optional now and
   is done for each line in a comment.
 * Added a JavaScript message extractor.
 * Updated to CLDR 1.6.
 * Fixed timezone calculations when formatting datetime and time values.
 * Added a `get_plural` function into the plurals module that returns the
   correct plural forms for a locale as tuple.
 * Added support for alias definitions in the CLDR data files, meaning that
   the chance for items missing in certain locales should be greatly reduced
   (ticket #68).
