Removed independent management server

World server now handles its own management-server-related functionality, a new management server will be written in the future to facilitate cross-world event syncing
World server now runs standalone, this requires the client to be configured to connect the world server port for the world list (world list was previously supplied by the management server on port 5555, which should be swapped to the world server port that is generally 43595 for world 1) work is in progress to update client launchers to make this as seamless as possible
This should resolve issues where players sometimes get a login error claiming they are already logged in
