Per-Player Random Respawn

This mod only needs to be installed on the server. It is configured entirely through the Minecraft console.

Commands:

Enable/disable random respawn globally:

/randomrespawn default true/false 

Set random respawn range (default is 10000):

/randomrespawn range 10000

Enable/disable random-respawn individually, per-player:

/randomrespawn set PlayerName true/false

How teleportation works:

The mod selects a random point within a radius from the 0,0 and checks it. If this chunk has never been loaded by players and the teleportation location is safe, the player is teleported there. If the chunk was discovered or place is unsafe, another point is selected with a slightly larger radius.

Why did I create this mod when there are already similar mods? Other mods either don't work or don't suit me in terms of functionality.
