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.
I guess it must not be a typo because you do it here too. Now I'm just curious what it means. :P
