Fix deprecation warnings for Gtk.Widget.render_icon 

[Gtk.Widget.render_icon](https://lazka.github.io/pgi-docs/#Gtk-3.0/classes/Widget.html#Gtk.Widget.render_icon)
has been deprecated since 3.0.

The replacement solution is to use Gtk.IconTheme.load_icon.

Most of `Gtk.STOCK_*` value are deprecated:
* `Gtk.STOCK_NEW` is now "document-new"
* `Gtk.STOCK_GO_FORWARD` is now "go-next"
* `Gtk.STOCK_GO_BACK` is now "go-previous"
