There might have been a bug in my Arch Linux installation of GNOME
Builder. I've now installed it the recommend way:

	flatpak install --from https://flathub.org/repo/appstream/org.gnome.Builder.flatpakref

Fixes #1.

This uses a new compiled jar based on the current `headless-stdin`
branch:
* https://code.briarproject.org/briar/briar/tree/3f6e5fe098a45977458e9f717418692105b81c61
* https://media.dorfbrunnen.eu/briar/jars/002/briar-headless.jar

Based on current master + clikt 1.7.0

Modules can't contain slashes and class names seem to follow CamelCase
style.

That's a binary prebuilt by me. Later, we should build it by source.

I would like to use v11 as v10 is already deprecated, but it fails when
building with that newer version.

Based on a template generate by Gnome Builder.
