Release: v0.13.1

The `versionCode` has been bumped to `1000` so that users who have installed from F-Droid or GitHub should not have the app attempted to be updated by Google PlayStore and failing and also shown in PlayStore app updates list due to non-collaborative `v0.14` app release on PlayStore that set the `versionCode` higher than the latest F-Droid or GitHub `13` release. Unlike F-Droid, PlayStore does not check for difference in app APK signature before attempting to download and then failing to install due to signature mismatch.
