    Revert "GtkHeaderBar: Allow window dragging"
    
    This reverts commit 30a1a79322f4097ce47c2a08678479d00cc54b69.
    
    This turns out to be unnecessary when you can set the titlebar
    on the window and let GtkWindow handle the events. As a benefit,
    we get the window menu on custom titlebars for free.
