This adds Twitter and Facebook sharing using the "Build your own Tweet button"
and Share Dialog methods, respectively. Both are javascript and iframe free;
instead you link to a specified url. For Twitter customization arguments
are sent through query parameters. Facebook requires you to put open graph
meta tags at the shared url.

Right now the user has to ensure their badge is made public before sharing.
Nothing stops you from sharing a private badge, but that link will be broken
when people try to visit it.
