Subject: [PATCH] Custom namespaces: To add a new namespace, just set
 $wgExtraNamespaces in LocalSettings.php. Custom namespaces must begin at 100.
 This is primarily intended to let us add a bunch of international versions of
 the "Help:" namespace on Meta, so we can finally have a single place for all
 documentation and easily dump/import it to other wikis.
