Start polishing graphics

0.1.1-alpha:

• Fix UI scaling problem when Window's scaling is different than 100%
• Add game version to main menu
• Start polishing visual elements of the game

What's next?

I am taking a break from coding new features and starting polishing existing ones. Before I move onto polishing systems I will polish visual elements of the game. I need a break from coding, and there is lots of small tasks I need to do about visuals.
