Update chunk rendering, improve chunk loading

- On world_init, LOAD_CHUNK amount of chunks are preloaded
- Chunks are loaded around the player's current chunk, in a square
  shape. The size of the shape is controlled by CHUNK_DISTANCE
- Allow chunks struct to be independent of a position. We load a chunk
  TO a position in the world chunk grid (x, y). This allows us to "wrap"
  chunks, so we have an endless world, but we are really just wrapping
  around
