debian-installer: Please update debconf PO translation for the package debian-installer

Hi,

After sending a call for updates for Debian Installer sublevel 1 a few
days ago, here is the same call for sublevel 2.

Once again, there is no strict deadline: I would just like to make
sure that we get some updates, after nearly 5 months since we released
wheezy and then since the last wide call for updates.

Please preferrably commit updates to the D-I SVN repository if you or
someone in your team has commit access there. If you don't, you can
send the update to me by praviate mail, as a last option.

Many thanks in advance.
