Bump version to 0.0.6

- Move the VARASYS logo to the right-hand control group (was left of the
  title).
- Alt+↑/↓ now seeds the cue when none is set, so reordering works without
  having to cue an item first (it was silently no-opping).
- Theme button uses plain glyphs (◐ system / ☀ light / ☾ dark) instead of
  the 🖥 emoji, which didn't render in some browsers.
