Julien "_FrnchFrgg_" RIVAUD 6a985df81e Replace positioning function with popup helper
Because all uses of the function positioning menus anchored to a widget
were as callback argument to Gtk::Menu::popup() where the caller needed
to correctly bind arguments, this led to repeated and a bit obscure code.

Wrap the logic into an helper function that takes care of all that, and
update the callers.
