Law School - Adding API attribute isLawStudent

Added attribute isLawStudent to /my/status API, removed previous isLawStudent method from academicsController.
Instead of a new API only for the isLawStudent flag, what about adding it to MyBadges::StudentInfo? (part of the Badges API) That's already dependent on a Bearfacts feed (RegBlocks) and is kind of the designated home for globally-used data that's not necessary for initial page load.
