Save update and config fix

- Changed save so that it uses the asynchronous save.  This will
eliminate any lag server lag during autosave.
- Configuration settings should now save properly when the server is
already running.  While changes won't go live until next restart, they
should save properly and run properly next time the server is run.
- Fixed the player list again, as it wasn't retrieving the steam user
list properly.
