Welcome back, gnome-main-menu!

I’m really happy to announce that gnome-main-menu will come back, adapted for MATE, with same name and with the source still on same location on git.gnome.org, as there is no reason to fork it.

Federico Mena Quintero accepted the proposal of me and Nelson Marques to continue to maintain it for MATE.

The next gnome-main-menu version will come out together with MATE 1.6.
