Spawn is now underground and the terrain is infinite

new build 2024-11-15

changelog:

• Spawn location is now underground. 
• The terrain infinitely grows in all directions.
• F12 takes a screenshot.

known issues:

• Performance eventually drops. It doesnt deload far away terrain yet. This is on top of the to do list. It's very important that the framerate stays good regardless of the size of your tunnel network.
• You can click infinitely far, so it is possible to dig a 'hole' in the world, because the terrain only generates up to a certain distance from the player. If you click fast enough you can dig straight down and fall out of the world.
• The movement (especially the jumping) isnt good yet. The focus for now is on getting the terrain to work, if there is nowhere to walk it doesnt really matter how smooth the walking is.
• The screenshot is saved in the main game folder, which is impractical.
• Ducking is not implemented. The keybind is assigned in the code but doesnt do anything useful yet.
• There is no audio yet.
