Chord 0.3.1

Chord notarized by Apple, an Update button like Arc's, a question before quitting,
and ⌘Y for the history.

Added

• When a new version of Chord is downloaded, an "Update Chord" button shows above the
  Spaces, like Arc's: a click restarts Chord on it. Left alone, it installs at the
  next quit.
• ⌘Q asks before quitting, like Arc, on a glass card over the window: Quit (↩),
  Cancel (esc) or "Quit and Don't Ask Again" (Settings › General › Ask before quitting
  turns it back on). ⌘Q again quits.
• ⌘Y shows the browsing history (History › Show All History, or "History" in the
  command bar).

Changed

• Chord is signed with a Developer ID and notarized by Apple: macOS opens it on first
  launch without a detour through Privacy & Security. Coming from an earlier version,
  macOS may ask once to let Chord use its keychain item.
• The archive no longer has a button at the bottom of the sidebar: it stays in
  File › Archived Tabs (⌥⌘A). The command bar's cheat sheet shows ⌘Y for the history
  in its place.

Fixed

• Submitting a form with an address no longer crashes Chord: "Save address?" and
  "Update address?" now show in Chord's prompt at the top of the page, like a site's
  permission. Saving a card or an IBAN shows no prompt for now (it crashed too).
