A polish translation of 2048++ strings

Hi,

I prepared the 100% polish translation. I didn't transalte 'free' and 'pro' words, bacause everyone in Poland will understand it. It this case 'free' stands for 'darmowa' and 'pro' for "płatna". If you want, I can transalte it too.
Is this a typo? I obviously don't know any Polish, but it looked a bit weird so I just wanted to confirm. :)
