Updated mediawiki/extensions
Project: mediawiki/extensions/MobileFrontend  26d86dd9f8eecfde2d47b961047ed06f68ba256c

New hook, MobileSkinCreated

Unlike EnterMobileMode, it gets run only if we enter mobile mode
AND are serving HTML/WML (i.e. not in api.php or load.php).

Its first use will be to move code adding some vary headers to
Zero. To simplify the transition, this code will be removed from MF
later.
