Upgrade MediaWiki to 1.19.9

[chris]

See the announcement email:

I would like to announce the release of MediaWiki 1.21.3, 1.20.8 and
1.19.9. These releases fix 2 security related bugs that could affect users
of MediaWiki. Download links are given at the end of this email.

* Kevin Israel (Wikipedia user PleaseStand) identified and reported two
vectors for injecting Javascript in CSS that bypassed MediaWiki's blacklist
(CVE-2013-4567, CVE-2013-4568).
<https://bugzilla.wikimedia.org/show_bug.cgi?id=55332>

* Internal review while debugging a site issue discovered that MediaWiki
and the CentralNotice extension were incorrectly setting cache headers when
a user was autocreated, causing the user's session cookies to be cached,
and returned to other users (CVE-2013-4572).
<https://bugzilla.wikimedia.org/show_bug.cgi?id=53032>


Additionally, the following extensions have been updated to fix security
issues:

* CleanChanges: MediaWiki steward Teles reported that revision-deleted IP's
are not correctly hidden when this extension is used (CVE-2013-4569).
<https://bugzilla.wikimedia.org/show_bug.cgi?id=54294>

* ZeroRatedMobileAccess: Tomasz Chlebowski reported an XSS vulnerability
(CVE-2013-4573).
<https://bugzilla.wikimedia.org/show_bug.cgi?id=55991>

* CentralAuth: MediaWiki developer Platonides reported a login CSRF in
CentralAuth (CVE-2012-5394).
