Release 0.2.0

A minor release, not 0.1.4 (the previous commit's number, never built or
tagged): it adds features. Since 0.1.3, from community contributions: an
interface in Russian and Simplified Chinese (Chinese drawn with the
system's own font); several apps can install at once with one password
prompt on Linux; a verified download is kept for a retry when its install
step fails; the window closes to the tray on Wayland; HTTPS certificates
are verified by the OS; Direct3D 12 by default on Windows (fixes a startup
crash on hybrid AMD laptops); app names centred on their icons.
