Event for item-request-proxy creation

[ILLISIS]

Greetings
Requesting for the ability to listen for item-request-proxy creation. Currently the only way to find them is to either 1) have the item-request-proxy created at the time of the ghost and listen for on_built_entity or 2) using surface.find_entity_filtered.

My suggestion is to simply raise on_built_entity when an item-request-proxy is created

This would especially useful for item-request-proxy entities created via the upgrade planner. There are only a few ways that an item-request-proxy can be created, and for most of them there are workarounds you can use (e.g. checking players' selected and opened). But when an item-request-proxy is created via the upgrade planner, if the entity prototype is the same, not on_marked_for_upgrade event (nor any other event) is fired for that entity.

If for whatever reason it's not feasible to have events for ever item-request-proxy creation, it would still be very useful to have an event fired for any entity that was affected by a use of the upgrade planner but that did not have an on_marked_for_upgrade event fired for it.

Okay, I just figured out that you can get events for item-request-proxy created by:

* Adding a created_effect with a "script" trigger item to the item-request-proxy prototype
* Subscribing to the on_script_trigger_effect event and filtering by effect_id
