Default Icon Theme 0.18 released!

Hello!

After a bit of time we have a bugfix and slight modernization release
of the default-icon-theme/hicolor-icon-theme project.

Please note that the project uses Meson by default now, instead of Autotool=
s.

Tarballs available here: https://icon-theme.freedesktop.org/releases/

Cheers,
