    Disable tab detaching to avoid crash
    
    As reported by Antonio Fernandes in:
    https://bugzilla.gnome.org/show_bug.cgi?id=781991#c1
    
    Detaching a notebook tab into a new window through DnD
    leaves Nautilus in an inconsistent state leading to a
    crash after loading a new location.
    
    As opening a folder into a new window should be done
    through its action already present in the folder context
    menu of both files view and path bar, let's disable this
    alternative way to do it through tab detaching, as
    Nautilus code was not expecting that use pattern.
    
    Closes #137
