Added Visual Effects & Skill Rendering 🚀

I worked on the visual side of Galactic Survivor today.

I added and improved the rendering for skill pickups, the player shield, berserk glow, fire chamber, plasma barrier, poison aura, magnet range, bullets, enemy bullets, and several ability effects.

I also added visual effects for lightning, explosions, shockwaves, black holes, time freeze, laser beams, fireball warnings, boss fire rings, teleporting, and rage mode.
