I think this branch is quite correct, however we cannot test it until GUI distinguishes (and sets) tear-off and submenus correctly

As I wrote in the gui PR, we need to change all the backends not just x11. Also this change needs to be checked on many window managers, especially on the one I am using (KDE). Otherwise we have an improvement for some, but a regression for others.

Of course, we need testing. Right now it appears to do no harm on windowmaker (but doesn't fix an annoying layering detail either). On Mac-X11 now all menus are movable, ont what we like, but more consistent. Will test xfce, please test kde.

I think freedesktop adherence is good. Reading the documentation, these styles were added specifically for NeXT style interface (!)
Currently, even with the gui change, submenus and teared-off menus are still the same, I'd like to fix that. Try on your side with props.
