[FR] Add featureDefID and teamID to FeatureCreated/Destroyed

The defID seems missing compared to most other objects. Also, the currently exposed value is the allyTeamID which is also backwards (you can get the allyTeamID from a teamID, but you can't disambiguate it the other way around).

Locate the definitions and consumers of the FeatureCreated and FeatureDestroyed events. Check how defID and allyTeamID are currently exposed, then update the event data so featureDefID and teamID are available with the requested team identity semantics; done means both events expose the requested values consistently.
