add fastlane support, including changelogs

[kasnder]

Thanks! Worked out fine.

One more question: I only see a single release there. What happened to the others? Shouldn't they have been kept?

PS: and would you accept a PR with the app's metadata in fastlane format, so you'd be in control how the app is presented, and can keep description & graphics in sync with development? There's always the IzzyOnDroid Fastlane Documentation for guidance when needed (and I am available for questions when needed, too).

Gladly, and yes, please ping me then! For now, existing things are enabled (shortdesc,fulldesc,icon,featureGraphic,screenshots) and will be synced with future releases.
