Changes

• Walls are now lowered when placing rooms/buildings.
  
  It ended up being pretty hard to place a building behind another building as you could only see where the wall was and not the border. This should hopefully solve that issue.
• Added another type of trash to make things look a bit more interesting.
• Trash now fades into the floor instead of just disappearing when cleaned up
• Fixed students missing lessons when loading a save file
  
  This would happen if you saved whilst a student was walking to a lesson, the game wouldn't save the fact they were walking and when it loaded the game again the student would assume it couldn't reach the room.
• Added basic command support support on the server console.
  
  Currently only "quit" and "save" for now.
• Redo the female student models. No longer a copy/paste job from the male model.
• Smooth shadow rendering, shows more on lower settings.
• Changed the rendering of shadows on water.
  
  This occurred due to an optimization on shadow rendering breaking the hack used for water shadows.
• Fixed some holes in a few models
• Modified the textures of doors and added a few new colors.
• Slowed down the snack stop's serving time and fixed a few issues with its script
  

Internal Changes

• Cleaned up some unused code/data from the old idle system
• Optimized shadow rendering slightly by doing it at a later rendering stage
• Animated model rendering improvements which should allow for slight differences in body shapes when sharing animations.
• Reduced the amount of VRAM required slightly by changing the types used for some framebuffers.
• Optimized the ECS used internally to save some memory
• Optimized some memory allocations in a few hotspots.
