Added built-in "Off" states to the cheats with parameters. This is
also the default state, obviating the need for a default value. Removed the "default" attribute as a result. Switching from "Off" to another state first executes the "on" script followed by the "change" script. Switching to "Off" from another state executes the "off" script. While not off, the "run" script is executed each frame.
