Hotfix for client disconnect errors.
Got rid of logging errors where it would say the connection did not close cleanly but it actually did.
Another small fix to prevent errors on aborted client connections.
Fixed trace logging error that would dump a bunch of output on a server broadcast.
Made error message clearer in starbound_config_manager
Simplified disconnection logic. I believe this *should* fix the player full message.
Merge branch 'development'

Conflicts:
	server.py
Removed trace message for release.
