Repeated intro

Hello! For this update I have worked mainly on optimizing the gravity algorithm and adding GPU support. Currently GPU doesn't grant a massive boost but any extra FPS are welcome! The performance on CPU has improved by roughly 63% and with the help of GPU, the total performance gain is roughly 82% with density color on (this is the most computationally expensive color mode and the one I used for testing). This is almost double the performance with GPU enabled!
