Add Wormhole Shader with Inward Movement Effect

[ragerin]

Summary

This PR introduces a new shader for the awesome wormhole graphic created by @aBlueShadow. The shader adds minor movement to the texture, simulating an inward pulling effect, as seen below.

Changes Made

• Shader file:
  • Created a new shader file (wormhole.shader) specifically for the wormhole graphic.
  • Implemented the logic to animate the texture with a pull-inward effect.
• ShaderRegistry:
  • Added a time uniform to the ShaderRegistry to support the new shader's animation needs.
• Wormhole SpaceObject:
  • Included the engine header to enable engine->getElapsedTime() for the uniform.
