    Allow non-editable cells to receive focus
    
    Slight tweak for GtkTreeView, also non-editable cells must be able to receive
    focus to get all keyboard navigation right.  This will be further tweaked
    to get focus siblings to work like focus cells did in GtkTreeView before
    refactoring.
