Changes:
* Rename now affects all instances where a player's name is shown. BYOND keynames can still be viewed by using the "Who" command.
* Sound alerts have been added. A sound will play whenever someone speaks or performs an action. These can be muted or unmuted by clicking "Toggle Sound" under the File menu.
* Added a "Set Timer" command. Players can now set timers to go off after a specified amount of time.
* The host can now save and load rule sets to external files.
