Release on F-Droid

• Public APK of app
• F-Droid Deployment

This issue might have popped up in the previous repo, but there are still people out there with custom ROMs and don't have Google services installed. Some can't access Google due to region-locking or just don't want to use the Playstore.

The thing that prevented it last time for it to be on the Open source store was that fdroid/rfp#97 (closed) the Cordova build required a Play-services fragment to be available during build. Maybe with the RN version it could be different.
