Changes:
- Added icon to both variants (thanks to @b3pio)
- Added fastlane metadata for F-Droid release (thanks to @IzzySoft)
Apart from that, this release has been created to include the basic variant in F-Droid (link). The Photos variant is not compatible with the F-Droid policy.
Furthermore, from now on I will provide signed release builds here on GitHub. Before installing, the old version must be uninstalled manually.
