Branch `broulik/gmenu-dbusmenu-proxy` of plasma-workspace
Tested `gedit` which supposedly only has a menu bar on Ubuntu

Tested LibreOffice 6 with `gtk3_kde5` platform plugin, should just work with regular GTK3 plugin

I won't be able to add any icons to LibreOffice's menus as the action names are random ids assigned by it. In gedit I get some names like "open" and "save" I could map on our side
Applications not having a dedicated menu bar will at least show the top panel menu with Settings, About, and Help

Does not work with Gimp or Inkscape as they aren't GTK3-based.
Out of the box it seems to work with most GTK3 apps (tried shotwell, gnome-builder, gnote, evince) and you get the "application menu" with few items like New Window, Options, Quit.
Together with appmenu-gtk-module and `GTK_MODULES=appmenu-gtk-module` I managed to get a full menu bar in pluma (editor),
