LibGUI: Notify widgets when their enabled state changes.
This is done by dispatching a (synchronous) "EnabledChange" event that can be picked up in change_event(). Use this event to kick widgets out of their "being pressed"-type modes if the user is interacting with them while the state is programmatically changed.
