Initial release.

• Toolbar popup: logins saved for the current site, one-click Fill,
  current TOTP codes, Lock.
• Optional in-page suggestions (off by default; enable per-site via
  Settings → "Suggestions in login fields"): click a login field to pick
  a saved credential, a one-time-code field to fill a TOTP code, or a
  new-password field to fill a generated password.
• Detects new or changed logins after a form submission and offers to
  save them.

This extension has no server and stores no data itself. It only talks,
over Firefox's Native Messaging API, to a companion desktop app
(HavenKeys) running on the same machine, which holds the encrypted
vault. See "Notes to Reviewer" for how to test both together.
