World Maintenance Bugfix

Due to variable shadowing, the world maintenance function was not properly maintaining the "unloaded" statistic.
Server Debug Logging API Update

Updated the server's debug logging API, making it threadsafe to add/remove items to be debug logged, and no turn debug logging on/off entirely.

This makes the system much more robust and useful.
Info Bugfix

Fixed a bug which was causing the information module's help to be built incorrectly.
Client Info Bugfix

Fixed a formatting error in the output of the client info module.
Log Through Chat

Added a module which allows server operators to receive the server log in realtime through in game chat.

This can be dynamically toggled on and off via the /log command, and defaults to being off.
World Information

Added a module which allows world information to be retrieved through chat by server operators.

Also added the necessary hooks to retrieve information from the World class.
