Tested Pluma (Gtk3), now has global menu
When module isn't installed, prints a warning on consoleTested Gimp and Inkscape, shouldn't be too bad
Unfortunately kde-gtk-config rewrites the `~/.gtkrc-2.0` whenever it changes its settingsnow have global menu
When module isn't installed, so this needs some more elaborate change to support (e.g.prints a warning on console, a `KDirWatch` that adds it back or something like this?)shouldn't be too bad
