Please update spanish translation of gnome-system-tools (other languages are also welcome)

["Jaap A. Haitsma" <jaap haitsma org>]

Hi,

I just added a new tango icon to the time-admin tool. For that I also
needed to update the screenshots of the documentation.
I noticed that the spanish translation is not really up to date for
that. So if somebody can take a look at that I would appreciate it.
Please send me a mail when it's updated. I can then update the
screenshots of the spanish manual

Thanks

Jaap

BTW I noticed that quite some languages haven't received much love
lately in gnome-system-tools.
