Support Syncthing

Syncthing has no official Javascript port. There's an unofficial node.js one that may or may not work in the browser. I'll leave this issue open for others to find, but I don't intend to implement this myself unless there is significant user demand.

Also there are currently no open source cloud storage options available with Tusk.

That's not true. Tusk supports any WebDAV implementation, including NextCloud and Owncloud. Source code for NextCloud is at https://github.com/nextcloud
