From: NGUYEN Kim Thuat <Kim-Thuat.Nguyen@xxxxxxxxxxxxxxx>
The current version of the git-remote-mediawiki supports only import and
export of plain wiki pages. This patch adds the functionality to export
file attachments (i.e. the content of the File: MediaWiki namespace),
which are also exposed by MediaWiki API.
This requires a recent version of MediaWiki::API (Version 0.37 works.
Version 0.34 doesn't).
