New app: Syncthing for Android

Closed username-removed-46616 requested to merge Zillode/fdroiddata:syncthing into master

A wrapper of syncthing for Android.

Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.
