[translations] update for l10n_server users

[Gábor Hojtsy]

Hey,

I just managed to level the differences between the 4 branches of potx
module, so now potx 5.x-1.2 contains the best code for you to
translate Drupal 6. Please do the following to continue Drupal 6
translation:

 - update to potx 5.x-1.2 (the latest stable version in the 1.x series)
 - update to the latest l10n_server development version (there were
some fixes related to export file placement, see
http://drupal.org/node/212594#comment-712331)
 - grab Drupal 6 RC3 and parse it in

You will notice that there are a small number of new strings to
translate due to potx finding stuff better and RC3 contains some
translatability fixes for strings which were not translated before.
Note that Drupal 6 final is expected for early next week. Use the flat
export format to export files and commit to drupal.org CVS, so your
translation will be available on launch.

Happy translating!

Gabor
