v0.9

Changes:

• Added a base enemy class and added enemy spawning
• A white square terraria slime type creature should spawn and hop around the world now
• Optimized chunk collision
  • Used to be a square collider for every block, now collision shapes will form together to make larger rectangles
  • A fully filled chunk will only have 4 collision shapes
• Optimized chunk spawning
  • Chunks now spawn around the player rather than all at once on planet load.
  • This saves on memory usage and collision detection, as well as makes it easier to work with in the code
• Planets can now be potentially way larger
  • Because of the chunk optimizations, planets can now be MASSIVE, at the cost of generation time of course
• Added a health bar that doesn't do anything as of now.
• Chunk optimizations also apply to ships
• Fixed bug where lakes would be filled with dropped sapling items
• Trees may be a little less common
• Added the noclip back, now u can scroll to change the speed
