EOG string addition announce

[Claudio Saavedra <csaavedra alumnos utalca cl>]

Hi dear documentors and translators,

I just committed a change which adds a pretty nice printing UI for the
Eye of GNOME, which adds several strings. I summarize the additions as
follows:

- 1 string in shell/eog-window.c
- many strings in the new file shell/eog-print-image-setup.c

Regarding changes in the UI, this adds a custom tab in the printing
dialog, namely, "Image Settings".

Best regards,

Claudio
