[wp-polyglots] Addition of Greek translation of Wordpress

[Simos Xenitellis]

Hi All,
Could you please add the Greek translation of WordPress to
http://svn.automattic.com/wordpress-i18n/

The file is available from
http://translate.os.cs.teiath.gr/el/wordpress/el_SX.po

Please rename the file to "el.po" when adding to trac.

BTW, we use a web-based translation tool to maintain translations, see
http://translate.os.cs.teiath.gr/el/
and this translation was a community effort (more than 8 people).

Regards,
Simos Xenitellis
