Port from stock properties etc. deprecated in GTK 3.10, use GtkfileChooserNative
Constants and methods related to stock icons were deprecated in GTK 3.10. Port away from these and use icon names to retrieve the icons from the theme instead.
While at it, also switch to GtkfileChooserNative
for the AT-SPI validator plugin.
(See individual commit messages for more details.)
