A badge definition should be able to award a badge to a user to provide a better API

While it is possible to get some specific users Badge instance and call .award() on it, it appears that a more common use might be to simply use the BadgeDefinition E.g. I have some BadgeDefinition called awesomeBadge and an implementer should be able to call awesomeBadge.award(someUser) which would find the users instance of that badge, and award it.
