Game Now has a Pretty Background

Hello! Pokitaire now has some very fancy background for you to look at while playing! While the flat green background was very good to make sure you aren't too distracted while playing, it looks extremely boring, so I made the background have a moving checkered pattern and some lava lamp looking noise.

I made sure to slow down the animated background for when you are in game so it isn't too distracting. And also another minor change that I hope you appreciate, because it was something that was bothering me for the longest time. The text on buttons now also indents themselves when pressing on them.

It was very fun to mess around in Godot's shader language and I really love how the game looks like right now with the animated background, even though this addition is not related to the next milestone at all. If you're wondering what that next milestone is, it'll be save data and game progression and beautifying the game should've come after, but I realize that it's a little dumb to wait around so long in making the game look good, so I'll just be sprinkling these types of additions while working on the aforementioned save data and game progression.
