Wormhole 0.3.0

Changed

• The app is now named Wormhole. On first launch, it moves existing data to ~/Library/Application Support/Wormhole and keeps a backup of the database. Your terminals, notes and settings are preserved.
• Terminals get WORMHOLE_* variables, and agent hooks from earlier versions are updated automatically.
• The app's macOS identifier has changed. You may need to allow notifications and grant other permissions again in System Settings. If Wormhole was your default terminal, it remains the default.
• To upgrade from 0.2.0 or earlier, download and install Wormhole from the website. Later updates can be installed from the app.
