Megrim v0.4.0

- History Calendar: tap a date to open, choose between, or start an
  entry for that day (backlog #9), including before any entries
  exist at all.
- Fixed Onboarding and Quick Log overflowing on small screens and in
  landscape.
- Fixed onboarding getting stuck spinning after Finish on some
  devices, despite the home location genuinely having saved.
- Analytics now shows a retry option instead of spinning forever on
  a failed load.
