--[[ Public function: Setup the spawner at pos.
This function blindly assumes there's actually a spawner at pos.
If not, then the results are undefined.
* Mob: ID of mob to spawn
All the following arguments are optional!
* MinLight: Minimum light to spawn (default: 0)
* MaxLight: Maximum light to spawn (default: 15)
* MaxMobsInArea: How many mobs are allowed in the area around the spawner (default: 3)
* PlayerDistance: Spawn mobs only if a player is within this distance; 0 to disable (default: 0)
* YOffset: Y offset to spawn mobs; 0 to disable (default: 0)
