Feature description
Have Last_Location disable per world option, so how it works is say i have a lobby, and that lobby has "last_location" disabled, then i have a survival world, and that world has "last_location" enabled

How the feature is useful
This is useful because if you have a lobby world and a survival world, you wouldn't want to spawn back where you were before in the lobby...

This is already possible, but is currently broken because of #367.

Oh... Sorry!
