event: Support a simple spy record

Browse source 
The current event spy is always passed the event context and the event.
The context is always NULL for a static spy. The event is not often used.

Introduce a 'simple' spy which takes no arguments. This allows us to drop
the adaptation code that many of these spy records use.

Update the event script to find these in the image.
