Link together /profile, /patient/new, and /patient/name

Variants and HLA types are loaded into the DB on file upload, along with patient name and patient notes. The /profile page displays a list of patients that a user owns, and the /patient/name page displays all patient-specific information (name, note, variants, HLA types).
Makes sense. (In this PR, I'm automatically choosing mhc_class=1. Obviously, that ain't right.)
