SaiLoR v0.6.1

A fix on top of v0.6.0's multi-reviewer support.

Fixed

• annotations and each reviewer's tree are now written in full — every field present, at
  its schema minimum, holding null/false where nobody has answered — instead of an empty {}
  for a fresh paper, or a missing key for a reviewer who hasn't started yet. That's what makes a
  reviewer's first real answer change a value on a line that was already there, rather than add
  a brand-new key: the shape a git diff stays readable through, and a git merge of two
  reviewers' independently-annotated copies of the same file actually survives.
• A file saved before this fix — or hand-edited — is corrected automatically the next time
  it's opened, and saved back if there's somewhere safe to save it. Nothing to do by hand.
