removing this dependency, as it's no longer used
now keeping track of the old data as well

"old data" == candidates from previous rounds
not stored as actual Candidate objects, just raw data
had to add new statuses as well
gave _data a predicate
updated display when an existing candidate is found
updated line numbers again (sigh)
now reading back data when loading a candidate

helps avoid out-of-sync data
added _read_candidate method to help with this
updated lunch interview invitations

new email addresses
added Albert
updated Location field
lunch invites now set SMS reminders for me
