v0.7.1

Features

• Custom titlebar — the app now uses a custom titlebar that matches the dark theme, replacing the native OS one.

Bug fixes

• Countdown parsing — countdowns longer than 59 seconds (e.g. "1 minute and 30 seconds") were not being parsed correctly.
• Avatar race condition — when two users sent messages in quick succession, both could end up showing the same avatar due to a race condition in the avatar cache.
