New polish translation for r 2543
I've updated translation - it's complete. I think there is a problem - some strings that I had previously translated disappeared and I had to translate it once more.
BTW. It would be nice to have a system to coordinate translations, something like www.translationproject.org. I work with it when I translate GNU Solfege (very nice program for ear training), and it's very useful. The translators always know when appears new version of a program they are working with.
