Updated mediawiki/extensions
Project: mediawiki/extensions/Widgets  0bb49ddcd139daa87dec38655e8ca11f4c62814f

Added 'noparse' and 'isHTML', apparently necessary for MW 1.21+

Also added a fix for a preg_replace() call that worked before; I don't
know why it stopped working, at least on my server, although I assume
it's related to some PHP update.
