v2.0.0 - big update!

Buncha updates:

• Fixed window size
  
• Improved click behavior
• Added win condition lol
  
• Added restart button
• Added title + feedback for which piece will be placed next
• Added feedback for which player's turn it is

I think it still needs additional feedback to make it more clear that you can overwrite squares, but after that it should be complete!
