window: remove custom get_preferred_width/height implementation
We already take care of the default size when we create the window, and these only break assumptions of the default GtkWindow's handlers.

Nautilus commit is from Feb 17, 2014 prior to release of GTK 3.14. Could not build against GTK 3.14 over GTK 3.22 system due to mate-desktop errors but should work as Nautilus used it with 3.14. Test builds with GTK 3.16 and 3.22 worked fine, no issues with saved or command line geometry

Replace size request code with padding code borrowed from Nemo. For some reason gtk_widget_set_margin_start(or end) does not throw GTK warnings when called on GTK_WIDGET(button_date->label) while  gtk_widget_set_size_request does throw warnings. Neither generates a build warning.

Stop the "allocating size of GtkButton <xxxx> without calling gtk_widget get preferred width/height()" warnings from caja-pathbar's slider buttons

Fix gtk_widget_create_pango_layout: assertion 'GTK_IS_WIDGET (widget)' failed warning and those descending from it. This does NOT fix the  gtk_widget_set_size_request: assertion 'GTK_IS_WIDGET (widget)' failed, which occurs because recent GTK3 versions warn that button_data is not a GtkWidget but still succeed in setting the size. Since GTK 3.22 will be the LAST version of GTK3 this won't break until GTK4 if ever.
Taking this out caused the pathbar buttons to jump on bold text so it had to be retained

Duplicate define of "CAJA_ACTION_UP_ACCEL" removed.
