Law School - Contextual Transcript Link

Added angular function to academicsController to check if user is a Law student. Changed transcript link from hard-coded link to angular variable that gets set to different link if user is a Law student.
@greytoyota can we use a regular if/else structure here? If `not law`, then do this, otherwise do something else. The reason for this is that the link will actually very briefly be the Tele-BEARS link.
