WikiHowProfile plugin; pulls avatar from WikiHow profile pages when registering or adding account with OpenID. (Full name, location, homepage, and bio are also on the profile page but not marked up in a way they can be easily retrieved yet.)

This is an additional plugin which piggybacks on OpenID authentication to pull
profile information from WikiHow user pages when creating or updating accounts.
WikiHow runs a customized MediaWiki setup, with locally-built extensions to add
profile features such as an avatar. As this additional info isn't yet exposed
through OpenID, we need to pull it separately.
