project: simplify focus chain
Nautilus classes add custom methods to grab the focus
differently according to the class.
The problem with this approach, however, is that we end
up with more code coupling, since it's necessary to include
more headers to use the custom grab methods.
To fix that, make classes override GtkWidget::grab_focus
method and remove the custom methods, so widgets can simply
call gtk_widget_grab_focus.
