Andreas Kling d12857fc36 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.
