Subject: [PATCH 2/2] Add webflow auth support to flatpak plugin

This is just the minimal support, launching the auth page in the default
web browser when libflatpak signals that we need to do the webflow auth.

Possible improvements could include doing either a webkitgtk dialog, or
maybe asking for confirmation before launching the web browser.
