Add a register_on_punch_entity()

[Bebibio]

Problem

Currently there is no possibility to track when an entity is dead in a mod (which doesn't add this entity).
There is already a function for player but not for entity.
Exemple: I want to know when an entity from an other mod is killed. But I can't!

Solutions

I'm don't really know how to add this in minetest's files but it will be a function that allows you to know when an entity is punch: minetest.register_on_punch_entity

Alternatives

No idea

You can. It's not the prettiest, but simply depending on said mod and "hooking" their entity definition to override the on_death callback works:

local def = minetest.registered_entities["their_mod:their_entity"]
local old_on_death = def.on_death
function def:on_death(killer, ...)
    -- do something
    return old_on_death(self, killer, ...)
end

This reduces this feature request to a lower priority matter of convenience.
