String addition and UI change in Gtk+

[Marek Kasik <mkasik redhat com>]

Hi,

I've just pushed a patch to Gtk+ which adds new string "_Remember
password". It is placed next to new check button in authentication
dialog. It is for storing password to gnome-keyring when printing to an
authenticated samba server.
See https://bugzilla.gnome.org/show_bug.cgi?id=674264 for additional info.

Regards

Marek
