Cleanup GTK examples.
Right now they emit warnings: ``` gtk_spreadsheet_sgskip.py:36: PyGTKDeprecationWarning: Using positional arguments with the GObject constructor has been deprecated. Please specify keyword(s) for "homogeneous, spacing" or use a class specific constructor. See: https://wiki.gnome.org/PyGObject/InitializerDeprecations vbox = Gtk.VBox(False, 8) gtk_spreadsheet_sgskip.py:39: PyGTKDeprecationWarning: Using positional arguments with the GObject constructor has been deprecated. Please specify keyword(s) for "label" or use a class specific constructor. See: https://wiki.gnome.org/PyGObject/InitializerDeprecations label = Gtk.Label('Double click a row to plot the data') gtk_spreadsheet_sgskip.py:51: PyGTKDeprecationWarning: Using positional arguments with the GObject constructor has been deprecated. Please specify keyword(s) for "model" or use a class specific constructor. See: https://wiki.gnome.org/PyGObject/InitializerDeprecations self.treeview = Gtk.TreeView(model) gtk_spreadsheet_sgskip.py:52: DeprecationWarning: Gtk.TreeView.set_rules_hint is deprecated self.treeview.set_rules_hint(True) ``` ``` pylab_with_gtk_sgskip.py:30: PyGTKDeprecationWarning: Using positional arguments with the GObject constructor has been deprecated. Please specify keyword(s) for "label" or use a class specific constructor. See: https://wiki.gnome.org/PyGObject/InitializerDeprecations button = Gtk.Button('Click me') ``` Fix that, and some more.
