Event for entity enabled/disabled by circuit condition

[sparr]

I need to know when a belt has been enabled/disabled for my belt overflow mod. It would be generally useful for other mods that apply to active but not inactive entities, as well.

You can check the control behavior on the belt to see if it's enabled or disabled. http://lua-api.factorio.com/latest/LuaC ... r.disabled

Checking every belt on the map every tick is prohibitively slow. I want an event so that I don't have to run any extra code if the belts aren't turning on/off.

I'm not adding an event when an entity goes active/inactive. It would fire too often and slow the entire game down.
