Description

Add Polish translation for #17

Additional comments:

1. You can notice that there are some extra spaces in end_message for polish-panels. The reason is that panel fits end_message and thankyou_message is quite long in Polish. Without these extra spaces the program looks like this
   
   And with extra spaces:
   
   This is a workaround but probably a better way is to fix cli.py to fit panels on the longer message, not always the end_message.
2. I work on Windows and to be able to run program on my machine, I needed to add encoding on config.py (otherwise there were errors). I made a separate commit with this change. It shouldn't affect other systems and allow Windows users to run program but it is up to maintainers if they want to merge this change
