Handle unloaded worlds on teleportation commands.

[cartman-2000]

It would be nice to have an unloaded world(An unloaded but not disabled world.) auto load when someone tries to use /home or /warp, or the other teleportation type commands, to go to a point in an unloaded world. At the moment, these commands just print out an error when a world the port is in isn't loaded, and the world has to be manually loaded with /world load worldname.

This could cause issues, as what if the world is unloaded by a server admin on purpose? They would not want players still able to override that and warp there. I'll think about this

You could add an option to the configs to either allow, or disallow the auto loading of a world when using a warp/home, you could give a general "World is unloaded." message when it's been disallowed. You could have the config options as either a global option, and/or a per world option.
