This is very similar to commitc6063183d3from master branch, except that I use the legacy tagged icon because GTK+2 does not have real symbolic icon theme support yet, which means that I would actually have to add the icon to all themes, and also revert colors and so on. That's just annoying so let's just use the color icon here, which will be the same fallback for all themes (even symbolic style ones). The icon used is the update one from: https://gitlab.gnome.org/GNOME/adwaita-icon-theme/-/blob/master/src/fullcolor/legacy/software-update.svg Also I use now the same hicolor/ theme overlay trick as in master since commite815c615e1so that I don't have to duplicate the work on all themes. Same as for the commit in master, licensing applies. This icon comes from the Adwaita repository and is therefore licensed under the terms of either the GNU LGPL v3 or Creative Commons Attribution-Share Alike 3.0 United States License.
