Make Keyboard shortcuts changeable again in ≥GTK+3.10 and GTK4
Former Title: Reimplement can-change-accels in ≥GTK+3.10 and GTK4
I have some shortcut conflicts so I set can-change-accels to true and this works fine with GTK+2 apps like pidgin, but shortcuts in GTK+3 apps like meld seem not to be changeable despite the option set..
