Get briar added to the main f-droid repo
The point is that people who have f-droid installed, but haven't added the briar repo (which presumably will continue to have beta releases for testers) will 1) see briar in the list of apps and 2) be able to install it with no effort.
This depends on #783 (closed), and then requires getting a build description added to f-droid's configuration.
(I'm really glad to see so much progress towards this overall goal.)
