Updated mediawiki/extensions Project: mediawiki/extensions/TitleBlacklist 52bab2daed0ee7df1f706372f42bbe57910bc3d4

(bug 36939) Introduce a way to limit username filter to certain sources.

• Name all sources and track them inside the entries. This should be fully backwards-compatible with previous configuration format, since numbers may be a legitimate source names as well.
• Introduce $wgTitleBlacklistUsernameSources as a variable which allows to specify which sources may be used for filtering usernames.
