[gtk+] Add settings for titlebar actions

    Add settings for titlebar actions
    
    These match the GSettings that mutter/metacity/gnome-shell have
    for this. We change the default for the middle-click action to
    none, since lower is just a terrible default.
    
    We're slightly bending the rules here, since we're adding new
    settings after .0, but a) it is just barely after .0, and b) settings
    are not really application API.
