debian-installer: Please update sublevel 4 of Debian Installer translations

Hi,

Yes, this is me again. I actually decided to really push hard for
Debian Installer translations completion to occur as soon as possible.
The planned release of Debian Wheezy is scheduled for "sometime in
2012". That may sound as distant, but my own experience proves that it
is not.

To  save you (and myself) a hassle when the release time approaches, I
will work hard (and then push you hard) to reach translation
completion for as many languages as possible, as soon aspossible.

At the moment I write it, 19 languages have reached full 100%
completion in all sublevels.

Yours can be another one.

For this, you need to complete "sublevel4" (remember
http://d-i.alioth.debian.org/doc/i18n/) and thus reach the completion
of "core" Debian Installer as seen on http://d-i.debian.org/l10n-stats/.

There is no file attached to this message, in hope that it guarantees
that it passes various spam filters.

All translators have commit access to D-I GIT and SVN. In case you're
among the very fewexceptions of people who don't, then please ask me
for the file in return. Otherwise, you'll find the file to update at
svn+ssh://svn.debian.org/svn/d-i/trunk/packages/po/sublevel4

PS to old timers among you: yes, I know that some of you only send
